[Greg Kroah-Hartman]

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

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

From: Wolfram Sang <wsa@xxxxxxxxxxxxx>

commit 1ef9f0583514508bc93427106ceef3215e4eb1a5 upstream.

Fix this from the logs:

usb 7-1: New USB device found, idVendor=046d, idProduct=08ca
...
usb 7-1: Warning! Unlikely big volume range (=3072), cval->res is probably wrong.
usb 7-1: [5] FU [Mic Capture Volume] ch = 1, val = 4608/7680/1
