4.18-stable review patch. If anyone has any objections, please let me know.
------------------
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.
