Merge tag 'sh-for-v6.9-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux

Pull sh updates from John Paul Adrian Glaubitz:
 "Two patches by Ricardo B. Marliere make two instances of struct
  bus_type in the interrupt controller driver and the DMA sysfs
  interface const since the driver core in the kernel is now able to
  handle that.

  A third patch by Artur Rojek enforces internal linkage for the
  function setup_hd64461() in order to fix the build of hp6xx_defconfig
  with -Werror=missing-prototypes"
