Subject[PATCH 4.18 050/168] ibmvnic: Include missing return code checks in reset function
Date
4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Falcon <tlfalcon@linux.vnet.ibm.com>

[ Upstream commit f611a5b4a51fa36a0aa792be474f5d6aacaef7e3 ]

Check the return codes of these functions and halt reset
in case of failure. The driver will remain in a dormant state
until the next reset event, when device initialization will be
re-attempted.
