ALSA: usb-audio: Add quirk flag for Sennheiser MOMENTUM 3
The Sennheiser MOMENTUM 3 is a wireless around-ear headphones featuring
ANC, which can be connected via Bluetooth or USB-C.
When connecting via USB-C, its UAC mixer works fine and precisely
corresponds to the reported dB range. However, the mixer's volume
GET_CUR method is somehow stubbed and returns a constant value (15dB).
Since commit 86aa1ea1f15c ("ALSA: usb-audio: Do not expose sticky
mixers"), the sticky check considers the mixer to be sticky and
unnecessarily disables the mixer.
Add a quirk table entry matching VID/PID=0x1377/0x6004 and applying
the MIXER_GET_CUR_BROKEN quirk flag, so that the mixer is usable again.
Quirky device sample:
