    Subject[ 09/91] regulator: core: Release regulator-regulator supplies on error
    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.
