3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiri Slaby <jslaby@suse.cz>
commit 4909a0caabb8b4352efcea223e58b86f8bc1f98b upstream.
bootresponse in snd_usb_mbox2_boot_quirk is only 12 (decimal) u8's long, but i9s passed to snd_usb_ctl_msg as it would be 0x12 (hexa) long. Fix that by having proper size of the array, i.e. 0x12.
