Subject: [PATCH 3/3] ASoC: wm8994: Report any low impedance accessory as a headphone
Date: Thu, 26 Jan 2012 19:16:02 +0000 [thread overview]
Message-ID: <1327605362-27065-3-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <1327605362-27065-1-git-send-email-broonie@opensource.wolfsonmicro.com>
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.
