From 02a32a92d4a123c75292a284bdc605c376d204f7 Mon Sep 17 00:00:00 2001 From: Soeren Moch Date: Thu, 20 Nov 2014 13:03:32 +0100 Subject: [PATCH] tbs2910: Fix error handling in board_mmc_init() When an invalid USDHC port is passed we should return -EINVAL instead of 0. Also, return the error immediately on fsl_esdhc_initialize() failure.
