Commit 140ea3bbf39a ("sd: use __register_blkdev to avoid a modprobe for an unregistered dev_t") removed blk_register_region(devt, ...) in sd_remove() and since then, devt is unused in sd_remove(). Hence, make W=1 warns: drivers/scsi/sd.c:3516:8: warning: variable 'devt' set but not used [-Wunused-but-set-variable] Simply remove this obsolete variable.
