Subject: [PATCH] video: fbdev: matrox: the list iterator can't be NULL
Date: Fri, 30 Jun 2017 08:00:30 +0000	[thread overview]
Message-ID: <20170630080030.2hee3stcmn5utlmc@mwanda> (raw)

My static checker is complaining because we check "drv" for NULL and
then we dereference it to get the next item in the list.  It can't be
NULL so we can remove this check.
