#1730417 — [PATCH] IB/core: fix incorrect fall-through on switch statement

FromColin King <colin.king@canonical.com>
Date2017-09-11 18:10 +0200
Subject[PATCH] IB/core: fix incorrect fall-through on switch statement
Message-ID<uozrA-5Ep-25@gated-at.bofh.it>
From: Colin Ian King <colin.king@canonical.com>

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.

Detected by CoverityScan CID#703125 ("Missing break in switch")

Fixes: fe2caefcdf58 ("RDMA/ocrdma: Add driver for Emulex OneConnect IBoE RDMA adapter")

Except the wrong title: IB/core -> IB/ocrdma
