[PATCH AUTOSEL 4.18 49/76] ibmvnic: Include missing return code checks in reset function

From: Sasha Levin
Date: Mon Sep 24 2018 - 10:49:21 EST


From: Thomas Falcon <tlfalcon@xxxxxxxxxxxxxxxxxx>

[ 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.
