Subject: [PATCH v2 07/13] ASoC: soc_bind_dai_link() directly returns success for a bound DAI link
Date: Thu, 5 Nov 2015 17:59:19 +0800 [thread overview]
Message-ID: <9cb8b4b46674b6688c92bf9c22f0cd9db1b86dff.1446717205.git.mengdong.lin@linux.intel.com> (raw)
In-Reply-To: <cover.1446717205.git.mengdong.lin@linux.intel.com>
From: Mengdong Lin <mengdong.lin@linux.intel.com>
This function will return success immediately for a bound DAI link.
No need to look for the cpu/codec DAIs again.
