From b84fff5afb16627a8973256992f3951ac3e90d84 Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Tue, 19 Apr 2016 13:12:43 +0800 Subject: [PATCH] ASoC: topology: Set the link ID when creating a FE DAI link Topology will set the link's generic id when creating a FE link. Device drivers can check the id for link specific initialization.
