Subject: scsi: smartpqi: wake up drives after os resumes from suspend
Git-commit: 2b447f811c1f7f30e4caa5a817d0c95d06aff874
Patch-mainline: v5.0-rc1
References: bsc#1133547
- set allow_restart option during scsi_device init.
This allows the kernel to send a START/STOP Unit command to the drive if
it encounters a 4/2 check condition in sense data.
