Subject: [alsa-devel] [PATCH] ASoC: kirkwood: fix external clock probe defer
Date: Wed, 23 Oct 2019 14:46:44 +0100	[thread overview]
Message-ID: <E1iNGyK-0004oF-6A@rmk-PC.armlinux.org.uk> (raw)

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")
