Subject: [PATCH 3.12 098/206] media: usb: uvc: add a quirk for Dell XPS M1330 webcam

From: Paul Fertser <fercerpav@...il.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 62ea864f84fed6e04dd033d500d4c9183a83d590 upstream.

As reported on [1], this device needs this quirk to be able to
reliably initialise the webcam.
