block: convert to device_add_disk()
For block drivers that specify a parent device, convert them to use device_add_disk(). This conversion was done with the following semantic patch: @@ struct gendisk *disk; expression E; @@ - disk->driverfs_dev = E; ... - add_disk(disk); + device_add_disk(E, disk); @@ struct gendisk *disk; expression E1, E2; @@ - disk->driverfs_dev = E1; ... E2 = disk; ... - add_disk(E2); + device_add_disk(E1, E2); ...plus some manual fixups for a few missed conversions. Cc: Jens Axboe <axboe@fb.com> Cc: Keith Busch <keith.busch@intel.com> Cc: Michael S.
