Subject: [PATCH 08/24] cdrom: remove the call to scsi_cmd_blk_ioctl from cdrom_ioctl
Date: Sat, 24 Jul 2021 09:20:17 +0200	[thread overview]
Message-ID: <20210724072033.1284840-9-hch@lst.de> (raw)
In-Reply-To: <20210724072033.1284840-1-hch@lst.de>

Only the sr driver can handle SCSI passthrough requests, so move the
call to scsi_cmd_blk_ioctl there.
