Subject: [PATCH 28/36] video: backlight: lcd: convert class code to use dev_groups

The dev_attrs field of struct class is going away soon, dev_groups
should be used instead.  This converts the video backlight lcd class
code to use the correct field.

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