    Subject[PATCH 3.16 086/370] ALSA: usb-audio: Add QuickCam Communicate Deluxe/S7500 to volume_control_quirks
    3.16.42-rc1 review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Con Kolivas <con@kolivas.org>

    commit 82ffb6fc637150b279f49e174166d2aa3853eaf4 upstream.

    The Logitech QuickCam Communicate Deluxe/S7500 microphone fails with the
    following warning.

    [ 6.778995] usb 2-1.2.2.2: Warning! Unlikely big volume range (=3072),
    cval->res is probably wrong.
    [ 6.778996] usb 2-1.2.2.2: [5] FU [Mic Capture Volume] ch = 1, val =
    4608/7680/1

    Adding it to the list of devices in volume_control_quirks makes it work
    properly, fixing related typo.
