A questionable development version was integrated for this SmPL script.

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/scripts/coccinelle/free/put_device.cocci?id=da9cfb87a44da61f2403c4312916befcb6b6d7e8

https://lore.kernel.org/cocci/201902191014156680299@zte.com.cn/


Now I am curious on how such a source code analysis approach will be
improved further.
Which changes will get the desired acceptance?
