ALSA: usb-audio: silence a static checker warning
We recently made "format" a u64 variable so now static checkers complain that this shift will wrap around if format is more than 31. I don't think it makes a difference for runtime, but it's simple to silence the warning. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
