Merge tag 'coccinelle-for-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull coccinelle semantic patch updates from Julia Lawall:

 - Update the semantic patches in the kernel that contain a URL for
   Coccinelle with a URL that is currently valid (from myself).

 - Add a semantic patch checking for unnecessary NULL tests on dev_{put,
   hold} functions (from Ziyang Xuan, followed bt a modification from
   myself).

 - Drop a semantic patch that replaces 0/1 by booleans, as this change
   was considered to be not worthwhile by some maintainers (from Steve
   Rostedt).

 - Extend an existing semantic patch with more checks for useless tests
   on variables addresses (from Jérémy Lefaure).
