Subject: [PATCH v6 01/10] ASoC: Intel: mfld-pcm: don't call trigger ops to DSP for internal streams
Date: Tue,  9 Sep 2014 15:11:24 +0530	[thread overview]
Message-ID: <1410255693-6958-2-git-send-email-subhransu.s.prusty@intel.com> (raw)
In-Reply-To: <1410255693-6958-1-git-send-email-subhransu.s.prusty@intel.com>

From: Vinod Koul <vinod.koul@intel.com>

For internal stream i.e. BE we have don't need trigger ops as that
would be handled by DAPM for us in subsequent patches
