[PATCH 07/15] genhd: Add attribute group parameter to device_add_disk

From: Fam Zheng
Date: Wed Aug 17 2016 - 03:27:33 EST

The added parameter attr_group, if not NULL, be added to the new disk.

The callers are converted with coccinelle:

@@
expression e1, e2;
@@
- device_add_disk(e1, e2);
+ device_add_disk(e1, e2, NULL);

So there is not behavior change yet.
