3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Brown <broonie@opensource.wolfsonmicro.com>
commit e81dba85c6388dfabcb76cbc2b8bd02836a53ae5 upstream.
If we fail while registering a regulator make sure we release the supply for the regulator if there is one.
