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.
