Fam Zheng Aug. 17, 2016, 7:15 a.m. UTC
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.
