From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
This patch updates aic94xx to set struct scsi_host_template->unlocked_qcmd=1
because it is using generic libsas sas_queuecommand() code which now can be
run without struct Scsi_Host->host_lock held following the original
host_lock unlock -> do_work() -> lock optimization in sas_queuecommand().
