From d6af507d5a568289a90984541e1b5971ede5cc9c Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Thu, 20 Nov 2014 16:35:16 -0200 Subject: [PATCH] mx51evk: 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.
