Subject: [PATCH 15/19] [media] uvc_video: Adjust one function call together with a variable assignment
Date: Sun, 25 Dec 2016 19:47:37 +0100	[thread overview]
Message-ID: <004f5e95-ac91-d643-d84b-a76e1da92577@users.sourceforge.net> (raw)
In-Reply-To: <47aa4314-74ec-b2bf-ee3b-aad4d6e9f0a2@users.sourceforge.net>

The script "checkpatch.pl" pointed information out like the following.

ERROR: do not use assignment in if condition

Thus fix the affected source code place.
