Subject[PATCH 18/36] regulator: convert class code to use dev_groups
Date
The dev_attrs field of struct class is going away soon, dev_groups
should be used instead. This converts the regulator class code to use
the correct field.

Mark, feel free to take this through your tree, or ACK it and I can take it
through mine.
