From 05beb8e012e8715f551d1fb2f2fa149f2a7dc06a Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sat, 15 Nov 2014 14:50:26 -0200 Subject: [PATCH] wandboard: 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.
