ALSA: usb-audio: Make mic volume workarounds globally applicable
Browse files Browse the repository at this point in the history 
[ Upstream commit d6e6b9218ced5249b9136833ef5ec3f554ec7fde ]

It seems that many webcams have buggy firmware and don't expose the
mic capture volume with the proper resolution.  We have workarounds in
mixer.c, but judging from the numbers, those can be better managed as
global quirk flags.
