From 0f791fdad82a02af013e4fc8c385dc690080c366 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Thu, 12 Sep 2013 15:36:34 +0200 Subject: [PATCH] mmc: core: Let mmc_set_signal_voltage take ocr as parameter This is yet another step of restructure code to be able to fixup the setup of the negotiated ocr mask.
