From 06564f60859bdf7e73d70ae35d7e285e96ae9c46 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 11 Sep 2017 17:03:13 +0100 Subject: [PATCH] IB/ocrdma: fix incorrect fall-through on switch statement In the case where mbox_status is OCRDMA_MBX_STATUS_FAILED and add_status is OCRDMA_MBX_STATUS_FAILED err_num is assigned -EAGAIN however the case OCRDMA_MBX_STATUS_FAILED is missing a break and falls through to the default case which then re-assigns err_num to -EFAULT. Fix this so that err_num is assigned to -EAGAIN for the add_status OCRDMA_MBX_STATUS_FAILED case and -EFAULT otherwise.
