Hi Avri,
Do you perhaps want me to integrate that information in the patch

No. But the Fixes tag seems strange, isn't it?
Right, that patch did not introduce the issue that
ufshcd_exception_event_handler() doesn't wait for ongoing SCSI command
dispatching calls. Let me look up which patch introduced that issue.
Thanks,
Bart.
