Subject: [PATCH 09/12] ASoC: cs42l42: Remove runtime_suspend/runtime_resume callbacks
Date: Tue, 10 Aug 2021 16:37:56 +0100	[thread overview]
Message-ID: <20210810153759.24333-10-rf@opensource.cirrus.com> (raw)
In-Reply-To: <20210810153759.24333-1-rf@opensource.cirrus.com>

The driver has runtime_suspend and runtime_resume callbacks, but
pm_runtime is never enabled so these functions won't be called, and
the runtime_suspend would cause jack detect to stop working.

These functions are unused - delete them.
