[ Upstream commit d26e9f669cc0a6a85cf17180c09a6686db9f4002 ]
Since 8b3a087f7f65 ("ALSA: usb-audio: Unify virtual type units type to UAC3 values") usb-audio is using UAC3_CLOCK_SOURCE instead of bDescriptorSubtype, later refactored with e0ccdef9265 ("ALSA: usb-audio: Clean up check_input_term()") into parse_term_uac2_clock_source().
This breaks the clock source selection for at least my 1397:0003 BEHRINGER International GmbH FCA610 Pro.
Fix by using UAC2_CLOCK_SOURCE in parse_term_uac2_clock_source().
