[PATCH 4.19 007/321] ASoC: kirkwood: fix external clock probe defer
From: Greg Kroah-Hartman
Date: Tue Dec 03 2019 - 17:47:04 EST
From: Russell King <rmk+kernel@xxxxxxxxxxxxxxx>
[ Upstream commit 4523817d51bc3b2ef38da768d004fda2c8bc41de ]
When our call to get the external clock fails, we forget to clean up
the enabled internal clock correctly. Enable the clock after we have
obtained all our resources.
Fixes: 84aac6c79bfd ("ASoC: kirkwood: fix loss of external clock at probe time")
