From f00ab14c252ac459e86194747a1f580ab503c954 Mon Sep 17 00:00:00 2001 From: Olof Johansson Date: Tue, 9 Feb 2016 09:34:30 -0800 Subject: [PATCH] mmc: block: return error on failed mmc_blk_get() This used to return -EFAULT, but the function above returns -EINVAL on the same condition so let's stick to that. The removal of error return on this path was introduced with b093410c9aef ('mmc: block: copy resp[] data on err for MMC_IOC_MULTI_CMD'). Fixes: b093410c9aef ('mmc: block: copy resp[] data on err for MMC_IOC_MULTI_CMD').
