Subject: [PATCH] ASoC: Intel: Skylake: Fix to fail safely if module not available in path
Date: Tue, 20 Dec 2016 12:46:45 +0530	[thread overview]
Message-ID: <1482218205-1067-1-git-send-email-subhransu.s.prusty@intel.com> (raw)

From: G Kranthi <gudishax.kranthikumar@intel.com>

If a module is not available in a pipeline, fail safely rather than
causing oops.
