[PATCH v2 2/3] block: convert to device_add_disk()

From: Dan Williams
Date: Fri Mar 11 2016 - 10:48:17 EST

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.
