From 4cbd52246533d1dc6449ef8278e95e5e0944a1e5 Mon Sep 17 00:00:00 2001 From: Kouichi Tomita Date: Sun, 15 Feb 2015 23:46:47 +0900 Subject: [PATCH] mmc: sh_mmcif: Move dev_err() of mmcif_timeout_work() If interruption of command already occurred, mrq pointer in dev_err() would refer to NULL, because the host-state is changed to STATE_IDLE and mrq pointer is changed to NULL by interrupt handler. Therefore dev_err is moved after checking STATE_IDLE.
