From 0aa6770000bafa65c17cf44b6619d328d4fc79b3 Mon Sep 17 00:00:00 2001 From: Philip Rakity Date: Sun, 27 May 2012 18:36:33 -0700 Subject: mmc: sdhci: only set 200mA support for 1.8v if 200mA is available max_current_caps can return 0 if not available from the sd controller. If no regulator is present or the regulator specifies a current less then 200ma, we no longer still set the 200mA caps bit anyway.
