Subject: [PATCH 01/15] disk: Drop add_disk in favor of device_add_disk
add_disk is now a "convenience" wrapper of device_add_disk. Unwrap it so
that callers can be later converted to handle error and attribute group
more easily.
Callers are converted with coccinelle:
@@
expression x;
@@
- add_disk(x)
+ device_add_disk(NULL, x)
Removal of add_disk and update of related comments are done manually.
