3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit ca0c37a0b489bb14bf3e1549e7a8d0c9a17f4919 upstream.
Driver allocated on stack struct regulator_config but didn't initialize
it fully. Few fields (driver_data, ena_gpio) were left untouched. This
lead to using random ena_gpio values as GPIOs for max77693 regulators.
On occasion these values could match real GPIO numbers leading to
interfering with other drivers and to unsuccessful enable/disable of
regulator.
