From 7bf38161af878935f5c04c503a136dd5d333cd9e Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Thu, 20 Nov 2014 16:35:20 -0200 Subject: [PATCH] mx53ard: 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.
