From 295070e9aa015abb9b92cccfbb1e43954e938133 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sat, 12 Nov 2016 15:22:38 +0100 Subject: [PATCH] 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.
