Merge tag 'sh-for-v6.11-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux

Pull sh updates from John Paul Adrian Glaubitz:
 "This is rather small this time and contains just three changes.

  The first change by Oscar Salvador drops support for memory hotplug
  and hotremove for sh as the kernel stopped supporting it on 32-bit
  platforms since 7ec58a2b94 ("mm/memory_hotplug: restrict
  CONFIG_MEMORY_HOTPLUG to 64 bit").

  That then results in a follow-up change to update all affected board
  config files.

  The third change comes from Jeff Johnson which adds the missing
  MODULE_DESCRIPTION() macro to the push-switch driver"
