Subject: [PATCH v2 10/14] ARM: OMAP/ASoC: Zoom2: Let the codec to handle the hs_extmute GPIO
Date: Tue, 14 Aug 2012 17:22:38 +0300	[thread overview]
Message-ID: <1344954162-7985-11-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1344954162-7985-1-git-send-email-peter.ujfalusi@ti.com>

Remove the use of set_hs_extmute callback and let the codec driver to
handle the extmute GPIO.
