Subject: ALSA: usb-audio: Fix invalid volume resolution for Logitech HD Webcam
 c310

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.
