3.16.52-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King <colin.k...@canonical.com>
commit 06564f60859bdf7e73d70ae35d7e285e96ae9c46 upstream.
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.

adapter")
