ALSA: usb-audio: Add quirk for Microsoft Modern Wireless Headset
Microsoft Modern Wireless Headset (appearing on the host as "Microsoft
USB Link") has a playback and a capture mixer volume/switch, but they
are fairly broken. The descriptor reports wrong dB ranges for
playback, and the capture volume/switch don't influence on the actual
recording at all. Moreover, there seem instabilities in the
connection, and at best, we should disable the runtime PM.
So this ended up with a quirk entry for:
- Correct the playback dB range;
I picked up some reasonable values but it's a guess work
- Disable the capture mixer;
it's completely useless and confuses PA/PW
- Suppress get-sample-rate, apply the delay for message handling,
and suppress the auto-suspend
The behavior of the wheel control on the headset is somehow flaky,
too, but it's an issue of HID.
