[alsa-devel] [PATCH 3/3] ASoC: wm8994: Report any low impedance accessory as a headphone

[Mark Brown]

Report any accessory with a low impedance as a headphone, previously
anything other than a short or microphone would not be reported at all.
The most likely reason is a microphone with incorrect polarity.
