Subject: [PATCH v2 08/13] ASoC: Bind new DAI links after probing components
Date: Thu, 5 Nov 2015 17:59:32 +0800 [thread overview]
Message-ID: <00d1b5793caa0959c5fe886445fb44785da2cf6b.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>
Probing components can bring new DAI or DAI links based on the topology
info. This patch finds the unbound DAI links and bind them.
