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.
