HID: hid-asus: Disable OOBE mode on the ProArt P16

The new ASUS ProArt 16" laptop series come with their keyboards stuck in
an Out-Of-Box-Experience mode. While in this mode most functions will
not work such as LED control or Fn key combos. The correct init sequence
is now done to disable this OOBE.

This patch addresses only the ProArt series so far and it is unknown if
there may be others, in which case a new quirk may be required.

HID: hid-steam: Make sure rumble work is canceled on removal

When a force feedback command is sent from userspace, work is scheduled to pass
this data to the controller without blocking userspace itself. However, in
theory, this work might not be properly canceled if the controller is removed
at the exact right time. This patch ensures the work is properly canceled when
the device is removed.

HID: core: Fix assumption that Resolution Multipliers must be in Logical Collections

A report in 2019 by the syzbot fuzzer was found to be connected to two
errors in the HID core associated with Resolution Multipliers.  One of
the errors was fixed by commit ea427a222d8b ("HID: core: Fix deadloop
in hid_apply_multiplier."), but the other has not been fixed.

This error arises because hid_apply_multipler() assumes that every
Resolution Multiplier control is contained in a Logical Collection,
i.e., there's no way the routine can ever set multiplier_collection to
NULL.  This is in spite of the fact that the function starts with a
big comment saying:

* "The Resolution Multiplier control must be contained in the same
* Logical Collection as the control(s) to which it is to be applied.
   ...
*  If no Logical Collection is
* defined, the Resolution Multiplier is associated with all
* controls in the report."
* HID Usage Table, v1.12, Section 4.3.1, p30
*
* Thus, search from the current collection upwards until we find a
* logical collection...

The comment and the code overlook the possibility that none of the
collections found may be a Logical Collection.

The fix is to set the multiplier_collection pointer to NULL if the
collection found isn't a Logical Collection.

Revert "HID: multitouch: Add support for lenovo Y9000P Touchpad"

This reverts commit 251efae73bd46b097deec4f9986d926813aed744.

Quoting Wang Yuli:

"The 27C6:01E0 touchpad doesn't require the workaround and applying it
would actually break functionality.

The initial report came from a BBS forum, but we suspect the
information provided by the forum user may be incorrect which could
happen sometimes. [1]

Further investigation showed that the Lenovo Y9000P 2024 doesn't even
use a Goodix touchpad. [2]

For the broader issue of 27c6:01e0 being unusable on some devices, it
just need to address it with a libinput quirk.

In conclusion, we should revert this commit, which is the best
solution."

HID: wacom: Initialize brightness of LED trigger

If an LED has a default_trigger set prior to being registered with
the subsystem, that trigger will be executed with a brightness value
defined by `trigger->brightness`. Our driver was not setting this
value, which was causing problems. It would cause the selected LED
to be turned off, as well as corrupt the hlv/llv values assigned to
other LEDs (since calling `wacom_led_brightness_set` will overite
these values).

This patch sets the value of `trigger->brightness` to an appropriate
value. We use `wacom_leds_brightness_get` to transform the llv/hlv
values into a brightness that is understood by the rest of the LED
subsystem.

platform/x86: asus-nb-wmi: Ignore unknown event 0xCF

On the Asus X541UAK an unknown event 0xCF is emited when the charger

    If (ACPS ())
    {
        ACPF = One
        Local0 = 0x58
        If (ATKP)

        }
    }
    Else
    {
        ACPF = Zero
        Local0 = 0x57
    }

    Notify (AC0, 0x80) // Status Change
    If (ATKP)
    {

    }

    Sleep (0x64)
    PNOT ()
    Sleep (0x0A)
    NBAT (0x80)

Ignore the 0xCF event to silence the unknown event warning.

BUG: non-zero pgtables_bytes on freeing mm: -16384

On LoongArch system, invalid huge pte entry should be invalid_pte_table
or a single _PAGE_HUGE bit rather than a zero value. And it should be
the same with invalid pmd entry, since pmd_none() is called by function
free_pgd_range() and pmd_none() return 0 by huge_pte_clear(). So single
_PAGE_HUGE bit is also treated as a valid pte table and free_pte_range()
will be called in free_pmd_range().

  free_pmd_range()
        pmd = pmd_offset(pud, addr);
        do {
                next = pmd_addr_end(addr, end);
                if (pmd_none_or_clear_bad(pmd))
                        continue;
                free_pte_range(tlb, pmd, addr);
        } while (pmd++, addr = next, addr != end);

Here invalid_pte_table is used for both invalid huge pte entry and
pmd entry.

Get rid of 'remove_new' relic from platform driver struct

The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

Pull i2c component probing support from Wolfram Sang:
"Add OF component probing.

  Some devices are designed and manufactured with some components having
  multiple drop-in replacement options. These components are often
  connected to the mainboard via ribbon cables, having the same signals
  and pin assignments across all options. These may include the display
  panel and touchscreen on laptops and tablets, and the trackpad on
  laptops. Sometimes which component option is used in a particular
  device can be detected by some firmware provided identifier, other
  times that information is not available, and the kernel has to try to
  probe each device.

  Instead of a delicate dance between drivers and device tree quirks,
  this change introduces a simple I2C component probe function. For a
  given class of devices on the same I2C bus, it will go through all of
  them, doing a simple I2C read transfer and see which one of them
  responds. It will then enable the device that responds"

strscpy: write destination buffer only once

The point behind strscpy() was to once and for all avoid all the
problems with 'strncpy()' and later broken "fixed" versions like
strlcpy() that just made things worse.

So strscpy not only guarantees NUL-termination (unlike strncpy), it also
doesn't do unnecessary padding at the destination.  But at the same time
also avoids byte-at-a-time reads and writes by _allowing_ some extra NUL
writes - within the size, of course - so that the whole copy can be done
with word operations.

It is also stable in the face of a mutable source string: it explicitly
does not read the source buffer multiple times (so an implementation
using "strnlen()+memcpy()" would be wrong), and does not read the source
buffer past the size (like the mis-design that is strlcpy does).

Finally, the return value is designed to be simple and unambiguous: if
the string cannot be copied fully, it returns an actual negative error,
making error handling clearer and simpler (and the caller already knows
the size of the buffer).  Otherwise it returns the string length of the
result.

However, there was one final stability issue that can be important to
callers: the stability of the destination buffer.

In particular, the same way we shouldn't read the source buffer more
than once, we should avoid doing multiple writes to the destination
buffer: first writing a potentially non-terminated string, and then
terminating it with NUL at the end does not result in a stable result
buffer.

Yes, it gives the right result in the end, but if the rule for the
destination buffer was that it is _always_ NUL-terminated even when
accessed concurrently with updates, the final byte of the buffer needs
to always _stay_ as a NUL byte.

[ Note that "final byte is NUL" here is literally about the final byte
  in the destination array, not the terminating NUL at the end of the
  string itself. There is no attempt to try to make concurrent reads and
  writes give any kind of consistent string length or contents, but we
  do want to guarantee that there is always at least that final
  terminating NUL character at the end of the destination array if it
  existed before ]

This is relevant in the kernel for the tsk->comm[] array, for example.
Even without locking (for either readers or writers), we want to know
that while the buffer contents may be garbled, it is always a valid C
string and always has a NUL character at 'comm[TASK_COMM_LEN-1]' (and
never has any "out of thin air" data).

So avoid any "copy possibly non-terminated string, and terminate later"
behavior, and write the destination buffer only once.

printf: Remove unused 'bprintf'

bprintf() is unused. Remove it. It was added in the commit 4370aa4aa753
("vsprintf: add binary printf") but as far as I can see was never used,
unlike the other two functions in that patch.

tools/power turbostat: Cache graphics sysfs file descriptors during probe

Snapshots of the graphics sysfs knobs are taken based on file
descriptors. To optimize this process, open the files and cache the file
descriptors during the graphics probe phase. As a result, the previously

tools/power turbostat: Consolidate graphics sysfs access

Currently, there is an inconsistency in how graphics sysfs knobs are
accessed: graphics residency sysfs knobs are opened and closed for each
read, while graphics frequency sysfs knobs are opened once and remain
open until turbostat exits. This inconsistency is confusing and adds
unnecessary code complexity.

Consolidate the access method by opening the sysfs files once and
reusing the file pointers for subsequent accesses. This approach
simplifies the code and ensures a consistent method for accessing
graphics sysfs knobs.

tools/power turbostat: Enhance platform divergence description

In various generations, platforms often share a majority of features,
diverging only in a few specific aspects. The current approach of using
hardcoded values in 'platform_features' structure fails to effectively
represent these divergences.

To improve the description of platform divergence:
1. Each newly introduced 'platform_features' structure must have a base,
typically derived from the previous generation.
2. Platform feature values should be inherited from the base structure
rather than being hardcoded.
This approach ensures a more accurate and maintainable representation of
platform-specific features across different generations.

Converts `adl_features` and `lnl_features` to follow this new scheme.

tools/power turbostat: Fix trailing '\n' parsing

parse_cpu_string() parses the string input either from command line or
from /sys/fs/cgroup/cpuset.cpus.effective to get a list of CPUs that
turbostat can run with.

The cpu string returned by /sys/fs/cgroup/cpuset.cpus.effective contains
a trailing '\n', but strtoul() fails to treat this as an error.

That says, for the code below
val = ("\n", NULL, 10);
val returns 0, and errno is also not set.

As a result, CPU0 is erroneously considered as allowed CPU and this
causes failures when turbostat tries to run on CPU0.

get_counters: Could not migrate to CPU 0
...
turbostat: re-initialized with num_cpus 8, allowed_cpus 5
get_counters: Could not migrate to CPU 0

Add a check to return immediately if '\n' or '\0' is detected.

tools/power turbostat: Allow using cpu device in perf counters on hybrid platforms

Intel hybrid platforms expose different perf devices for P and E cores.
Instead of one, "/sys/bus/event_source/devices/cpu" device, there are
"/sys/bus/event_source/devices/{cpu_core,cpu_atom}".

This, however makes it more complicated for the user,
because most of the counters are available on both and had to be
handled manually.

This patch allows users to use "virtual" cpu device that is seemingly
translated to cpu_core and cpu_atom perf devices, depending on the type
of a CPU we are opening the counter for.

PCI/pwrctrl: Unregister platform device only if one actually exists

If a PCI device has an associated device_node with power supplies,
pci_bus_add_device() creates platform devices for use by pwrctrl.  When the
PCI device is removed, pci_stop_dev() uses of_find_device_by_node() to
locate the related platform device, then unregisters it.

But when we remove a PCI device with no associated device node,
dev_of_node(dev) is NULL, and of_find_device_by_node(NULL) returns the
first device with "dev->of_node == NULL".  The result is that we (a)
mistakenly unregister a completely unrelated platform device, leading to
issues like the first trace below, and (b) dereference the NULL pointer
from dev_of_node() when clearing OF_POPULATED, as in the second trace.

Unregister a platform device only if there is one associated with this PCI
device.  This resolves issues seen when doing:

  # echo 1 > /sys/bus/pci/devices/.../remove

Sample issue from unregistering the wrong platform device:

"Here is the 'big and hairy' char/misc/iio and other small driver

   - rust misc driver bindings and other rust changes to make misc
     drivers actually possible.

     I think this is the tipping point, expect to see way more rust
     drivers going forward now that these bindings are present. Next
     merge window hopefully we will have pci and platform drivers
     working, which will fully enable almost all driver subsystems to
     start accepting (or at least getting) rust drivers.

     This is the end result of a lot of work from a lot of people,
     congrats to all of them for getting this far, you've proved many of
     us wrong in the best way possible, working code :)

   - IIO driver updates, too many to list individually, that subsystem
     keeps growing and growing...

Merge tag 'driver-core-6.13-rc1' of git://git./linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH:
"Here is a small set of driver core changes for 6.13-rc1.

  Nothing major for this merge cycle, except for the two simple merge
  conflicts are here just to make life interesting.

  Included in here are:

   - sysfs core changes and preparations for more sysfs api cleanups
     that can come through all driver trees after -rc1 is out

   - fw_devlink fixes based on many reports and debugging sessions

   - list_for_each_reverse() removal, no one was using it!

   - last-minute seq_printf() format string bug found and fixed in many
     drivers all at once.

   - minor bugfixes and changes full details in the shortlog"
