Acquire the /RESET GPIO before we enable regulators and hold the device in reset while the regulators power up in order to improve robustness during the initial power up. Also fix the error path so that the device is left in reset while we're at it. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
