[PATCH AUTOSEL 4.14 04/21] ASoC: core: lock client_mutex while removing link components

[Sasha Levin]

From: Ranjani Sridharan <ranjani.sridha...@linux.intel.com>

[ Upstream commit 34ac3c3eb8f0c07252ceddf0a22dd240e5c91ccb ]

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.
