Subject: PowerCap: Convert class code to use dev_groups
X-Git-Tag: next-20131024~7

PowerCap: Convert class code to use dev_groups

The newly added power capping framework uses the obsolete .dev_attrs
field of struct class. However this field will be removed in 3.13, so
convert the code to use the .dev_groups field instead.
