Subject[PATCH 05/36] dma: convert dma_devclass 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 dma dma_devclass code to use
the correct field.

Dan and Vinod, feel free to apply this to your trees, or ACK it and I can take
it through mine.
