Subject: [PATCH 08/13] ASoC: Intel: reset the DSP while suspending
Date: Thu, 12 Feb 2015 10:00:00 +0530	[thread overview]
Message-ID: <1423715405-4562-9-git-send-email-vinod.koul@intel.com> (raw)
In-Reply-To: <1423715405-4562-1-git-send-email-vinod.koul@intel.com>

The manual recommends that we reset the DSP when we suspend so add that in
runtime suspend handler
