| Subject: regulator: stw481x-vmmc: fix ages old enable error |
| |
| From: Linus Walleij <linus.walleij@linaro.org> |
| |
| commit 295070e9aa015abb9b92cccfbb1e43954e938133 upstream. |
| |
| 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") |
