Takashi Iwai f4351a199c ALSA: usb-audio: Avoid access before bLength check in build_audio_procunit()
The parser for the processing unit reads bNrInPins field before the
bLength sanity check, which may lead to an out-of-bound access when a
malformed descriptor is given.  Fix it by assignment after the bLength
check.
