From e37197acad30928b434c54842642b11ce5f3639b Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Fri, 21 Nov 2014 16:42:56 -0200 Subject: [PATCH] ot1200: 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.
