Merge tag 'fallthrough-pseudo-keyword-5.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux

Pull 'fallthrough' keyword conversion from Gustavo A. R. Silva:
 "A tree-wide patch that replaces tons (2484) of /* fall through */
  comments, and its variants, with the new pseudo-keyword macro
  fallthrough[1]. Also, remove unnecessary fall-through markings when it
  is the case.

  There are currently 1167 intances of this fallthrough pseudo-keyword
  macro in mainline (5.9-rc2), that have been introduced over the last
  couple of development cycles:

    $ git grep -nw 'fallthrough;' | wc -l
    1167

  The global adoption of the fallthrough pseudo-keyword is something
  certain to happen; so, better sooner than later. :) This will also
  save everybody's time and thousands of lines of unnecessarily
  repetitive changelog text.

  After applying this patch on top of 5.9-rc2, we'll have a total of
  3651 instances of this macro:

    $ git grep -nw 'fallthrough;' | wc -l
    3651

  This treewide patch doesn't address ALL fall-through markings in all
  subsystems at once because I have previously sent out patches for some
  of such subsystems separately, and I will follow up on them; however,
  this definitely contributes most of the work needed to replace all the
  fall-through markings with the fallthrough pseudo-keyword macro in the
  whole codebase.

  I have build-tested this patch on 10 different architectures: x86_64,
  i386, arm64, powerpc, s390, sparc64, sh, m68k, powerpc64 and alpha
  (allyesconfig for all of them). This is in linux-next already and
  kernel test robot has also helped me to successfully build-test early
  versions of this patch[2][3][4][5]"
