ALSA: usb-audio: Fix missing endian conversion
The UAC2 jack detection support introduced the bmControls checks in a couple of places, but they forgot the endian conversion; the bmControls of UAC2 terminal descriptor is __le16, not a byte like in UAC1. Fixes: 5a222e849452 ("ALSA: usb-audio: UAC2 jack detection") Tested-by: Andrew Chant <achant@google.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
