regulator: stw481x-vmmc: fix ages old enable error
The regulator has never been properly enabled, it has been dormant all the time. It's strange that MMC was working at all, but it likely worked by the signals going through the levelshifter and reaching the card anyways. Fixes: 3615a34ea1a6 ("regulator: add STw481x VMMC driver") Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
