X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7c08b51f2fbb76b768d78ca6b0e13155d2c1e811;p=linux-beck.git

ASoC: wm8994: Report any low impedance accessory as a headphone

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.
