Merge branch 'for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/jlawall/linux

Browse Source 
Pull coccinelle updates from Julia Lawall:
 "Remove some semantic patches and remove a maintainer.

  Qing Wang <wangqing@vivo.com> reported that fen.cocci mostly finds
  false positives, so it is dropped.
  scripts/coccinelle/iterators/for_each_child.cocci also subsumes it, in
  a more correct way.

  Matthew Wilcox <willy@infradead.org> reported that bugon.cocci mostly
  gives false positives. It is an old script and was designed to be
  inaccurate to maximally cover problems, but most of what it is useful
  for has been done already.

  Gilles Muller passed away and is thus dropped from the maintainers
  list"

* 'for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/jlawall/linux:
  drop fen.cocci
  scripts/coccinelle: drop bugon.cocci
