From 7c08b51f2fbb76b768d78ca6b0e13155d2c1e811 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 26 Jan 2012 18:33:24 +0000 Subject: [PATCH] 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.
