Subject: [PATCH] ibmvnic: Include missing return code checks in reset function
References: bnc#1107966
Patch-mainline: v4.19-rc3
Git-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.
