Merge tag 'sh-for-v6.10-tag1' of git://git./linux/kernel/git/glaubitz/sh-linux

Pull sh updates from John Paul Adrian Glaubitz:
 "The majority of improvements are coming from Geert Uytterhoeven who
  took the time to fix a total of 30 cases of "-Wmissing-prototypes"
  compiler warnings, either by adding a missing header include, defining
  the missing forward declarations or making the functions in question
  static.

  In the case of several DMA functions, the fix was to actually just
  remove them as they were added but never used. Another one of these
  warnings was eliminated by removing the left-over sh5 cache handling
  support, a change that was suggested by Yoshinori Sato and, finally,
  the last of these warnings was fixed by guarding the function
  setup_profiling_timer() with CONFIG_PROFILING.

  While at it, Geert also removed two unneeded casts to kprobe_opcode_t
  in the kprobes code.

  Another change was contributed by Guenter Roeck to fix errors that
  were reported during checksum unit tests. The fix actually reverts the
  older change cadc4e1a2b4d ("sh: Handle calling csum_partial with
  misaligned data") which turned to be incorrect. It remains to be
  investigated whether there is a better way to handle misaligned data
  in csum_partial().

  A small fix contributed by Krzysztof Kozlowski drops the incorrect SPI
  controller spi-max-frequency property in the device tree source file
  for the J2 device platform while Uwe Kleine-König converted the
  push-switch driver to have its callback function return void, a change
  that is currently being applied to all drivers throughout the kernel
  in order to avoid resource leaks.

  Last but not least, Artur Rojek has fixed the IOPORT base address for
  the Sega Dreamcast platform which allows the Linux kernel to be
  successfully booted on this once popular video game console for the
  first time since a long time ago"
