Merge tag 'm68k-for-v5.12-tag2' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k

Pull m68k fix from Geert Uytterhoeven:
 "Fix virt_addr_valid() W=1 compiler warnings.

  This is a single non-critical fix. As the build bots are now testing
  all new code with W=1, these warnings are popping up everywhere,
  confusing people. Hence I think it makes sense to silence it as soon
  as possible"
