From 0268abf95f935c2fe45f778b2a223685e68c7823 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 24 Mar 2009 12:15:54 +0000 Subject: [PATCH] OMAP: mmc_twl4030 nicely disable vmmc_aux The MMC driver turns the power off before it turns it on. To avoid regulator warnings, vmmc_aux must only be disabled if it has previously been enabled.
