Subject: [PATCH AUTOSEL 6.6 04/21] ASoC: cs42l43: Handle error from devm_pm_runtime_enable

From: Charles Keepax <ckeepax@...nsource.cirrus.com>

[ Upstream commit d1722057477a3786b8c0d60c28fc281f6ecf1cc3 ]

As devm_pm_runtime_enable can fail due to memory allocations, it is
best to handle the error.
