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

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). * tag 'coccinelle-for-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/jlawall/linux: update Coccinelle URL coccinelle: free: add version constraint scripts/coccinelle/free: add NULL test before dev_{put, hold} functions coccinelle: Remove script that checks replacing 0/1 with false/true in functions returning bool coccinelle: Extend address test from ifaddr semantic patch to test expressions
