Subject: [PATCH] scsi: megaraid_sas: Call megasas_complete_cmd_dpc_fusion
every 1 second while there are pending commands
References: bsc#1049528,FATE#322937
Git-commit: 14298cf3207803b48d7b132fa7ddfd2433ba4f62
Patch-Mainline: v4.14-rc1
megasas_wait_for_outstanding_fusion checks for pending commands every 1
second. But megasas_complete_cmd_dpc_fusion is only called every 5
seconds. If the commands are already completed by firmware, there is an
additional delay of 5 seconds before driver will process completion for
these commands.
