Subject: [PATCH 13/16] ASoC: Intel: Skylake: read params from DSP if module is on
Date: Sat, 28 Nov 2015 15:01:58 +0530	[thread overview]
Message-ID: <1448703121-5831-14-git-send-email-vinod.koul@intel.com> (raw)
In-Reply-To: <1448703121-5831-1-git-send-email-vinod.koul@intel.com>

From: Omair M Abdullah <omair.m.abdullah@intel.com>

If a module is ON then we should read the module parameters from
DSP rather than driver cached values
