Subject: scsi: mpi3mr: Clean up block devices post controller reset
From: Chandrakanth patil <chandrakanth.patil@xxxxxxxxxxxx>
commit c01d515687e358b22aa8414d6dac60d7defa6eb9 upstream.
After a controller reset, if the firmware changes the state of devices to
"hide", then remove those devices from the OS.
