Subject[PATCH 3.16 087/136] ASoC: kirkwood: fix external clock probe defer
3.16.80-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Russell King <rmk+kernel@armlinux.org.uk>

commit 4523817d51bc3b2ef38da768d004fda2c8bc41de upstream.

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")
