From 07d83cc9c839a5f05c7c1b6d823a8f483bda0441 Mon Sep 17 00:00:00 2001 From: Grazvydas Ignotas Date: Mon, 23 Mar 2009 18:23:47 -0700 Subject: [PATCH] ARM: OMAP3: mmc-twl4030 add MMC3 support, v2 Device connected to MMC3 is assumed to be self-powered, so set_power() function is empty. It can't be omited because host driver requires it. Array size for hsmmc[] is specified to allocate to allocate an instance for the third MMC controller. Also fix a leak which happens if invalid controller id is passed.
