From edefcdad6a57657a236638c937ccd5a3af272d02 Mon Sep 17 00:00:00 2001 From: Ricardo Neri Date: Sun, 27 Nov 2011 16:18:01 -0600 Subject: [PATCH] ASoC: OMAP: HDMI: Move HDMI codec trigger function to generic HDMI driver The function hdmi_audio_trigger is a callback used by ASoC to stop/start HDMI audio. Also, it does not perform IP-specific configuration directly. Hence, it should be placed in the general portion of the HDMI driver, along with the other ASoC callbacks. Also, make this function static.
