sound/usb/pcm.c: In function ‘snd_usb_hw_params’:
sound/usb/pcm.c:494:31: warning: unused variable ‘format’ [-Wunused-variable]
sound/usb/pcm.c:494:15: warning: unused variable ‘channels’ [-Wunused-variable]
sound/usb/pcm.c:509:15: warning: ‘rate’ may be used uninitialized in this function [-Wuninitialized]
