[PATCH] regulator: fixed: Rely on the core freeing the enable GPIO

[Mark Brown <broonie@kernel.org>]

In order to simplify ownership rules for enable GPIOs supplied by drivers
regulator_register() always takes ownership of them, even if it ends up
failing for some other reason. We therefore should	not free the GPIO if
registration fails but just let the core worry about things.
