As reported by Dan Carpenter: FYI, there are new smatch warnings show up in tree: git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next master head: da17d7bda957ae4697b6abc0793f74fb9b50b58f commit: 4c3bdb5e2f5612ceb99ac17dbbe673b59a94d105 [media] siano: better debug send/receive messages drivers/media/common/siano/smscoreapi.c:396 smscore_translate_msg() error: buffer overflow 'siano_msgs' 401 <= 401 While it is almost impossible for this error to happen in practice, as it would require the siano's firmware to return an special invalid answer to a message request, fixing it is trivial. So, let's do it.
