Takashi Iwai [Mon, 17 Jun 2013 08:25:02 +0000 (10:25 +0200)]
commit 36691e1be6ec551eef4a5225f126a281f8c051c2 upstream.

Just like the previous fix for LogitechHD Webcam c270 in commit
11e7064f35bb87da8f427d1aa4bbd8b7473a3993, c310 model also requires the
same workaround for avoiding the kernel warning.
