pinctrl: airoha: Add support for EN7581 SoC

Introduce pinctrl driver for EN7581 SoC. Current EN7581 pinctrl driver
supports the following functionalities:
- pin multiplexing
- pin pull-up, pull-down, open-drain, current strength,
  {input,output}_enable, output_{low,high}
- gpio controller
- irq controller

pinctrl: canaan: Add support for k230 SoC

Configuration of the K230 is similar to that of the K210. However, in
K210, the 256 functions for each pin are shared, whereas in K230,
multiplex functions are different for every pin.

`drv_data` of `pinctrl_pin_desc` is pointing to currently activated
group, which is used to print the name of current function of pin in
`pin_dbg_show` and will be updated in `set_mux`, so they are not set
const.

ARM: imx: Allow user to disable pinctrl

Making pinctrl drivers and subsequently the pinctrl framework
user-controllable, allows building a kernel without this.
While in many (most) cases, this could make the system unbootable, it
does allow building smaller kernels for those situations where picntrl
is not needed.

One such situation is when building a kernel for NXP LS1021A systems,
which does not have run-time controllable pinctrl, so pinctrl framework
and drivers are 100% dead-weight.

Linux 6.12-rc1

x86: kvm: fix build error

The cpu_emergency_register_virt_callback() function is used
unconditionally by the x86 kvm code, but it is declared (and defined)
conditionally:

  #if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD)
  void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback);
  ...

leading to a build error when neither KVM_INTEL nor KVM_AMD support is
enabled:

  arch/x86/kvm/x86.c: In function ‘kvm_arch_enable_virtualization’:
  arch/x86/kvm/x86.c:12517:9: error: implicit declaration of function ‘cpu_emergency_register_virt_callback’ [-Wimplicit-function-declaration]
  12517 |         cpu_emergency_register_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu);

  12522 |         cpu_emergency_unregister_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu);
        |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix the build by defining empty helper functions the same way the old
cpu_emergency_disable_virtualization() function was dealt with for the
same situation.

Maybe we could instead have made the call sites conditional, since the
callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak
fallback.  I'll leave that to the kvm people to argue about, this at
least gets the build going for that particular config.

 "Assorted minor syzbot fixes, and for bigger stuff:

  Fix two disk accounting rewrite bugs:

   - Disk accounting keys use the version field of bkey so that journal
     replay can tell which updates have been applied to the btree.

     This is set in the transaction commit path, after we've gotten our
     journal reservation (and our time ordering), but the
     BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay
     uses was incorrectly skipping this for new updates generated prior
     to journal replay.

     This fixes the underlying cause of an assertion pop in
     disk_accounting_read.

   - A couple of fixes for disk accounting + device removal.

     Checking if acocunting replicas entries were marked in the
     superblock was being done at the wrong point, when deltas in the

Reduce Coccinelle choices in string_choices.cocci

The isomorphism neg_if_exp negates the test of a ?: conditional,
making it unnecessary to have an explicit case for a negated test
with the branches inverted.

At the same time, we can disable neg_if_exp in cases where a
different API function may be more suitable for a negated test.

Finally, in the non-patch cases, E matches an expression with
parentheses around it, so there is no need to mention ()
explicitly in the pattern.  The () are still needed in the patch
cases, because we want to drop them, if they are present.

coccinelle: Remove unnecessary parentheses for only one possible change.

The parentheses are only needed if there is a disjunction, ie a
set of possible changes. If there is only one pattern, we can
remove these parentheses. Just like the format:

  -  x
  +  y

not:

  (
  -  x
  +  y
  )

coccinelle: Add rules to find str_yes_no() replacements

As other rules done, we add rules for str_yes_no()
to check the relative opportunities.
