Takashi Iwai 47f25441ff ALSA: usb-audio: Add sanity checks in v2 clock parsers 
commit 0a62d6c966 upstream.

The helper functions to parse and look for the clock source, selector
and multiplier unit may return the descriptor with a too short length
than required, while there is no sanity check in the caller side.
Add some sanity checks in the parsers, at least, to guarantee the
given descriptor size, for avoiding the potential crashes.

Fixes: 79f920fbff ("ALSA: usb-audio: parse clock topology of UAC2 devices")
