commit 34ac3c3eb8f0c07252ceddf0a22dd240e5c91ccb
Author: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>
Date:   Thu May 23 10:12:01 2019 -0700

    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.
