From 34ac3c3eb8f0c07252ceddf0a22dd240e5c91ccb Mon Sep 17 00:00:00 2001 From: Ranjani Sridharan Date: Thu, 23 May 2019 10:12:01 -0700 Subject: ASoC: core: lock client_mutex while removing link components Removing link components results in topology unloading. So, acquire the client_mutex before removing components in soc_remove_link_components. This will prevent the lockdep warning seen when dai links are removed during topology removal.
