This patch looks fine, but when you send multiple patches applying
to a given driver, please indicate the order in which they should be
applied.
There are 3 options for this.
1. Put the patches all in one series, ordering obvious.
2. List all expected ordering in each patch.
3. Only send me on 'set' at a time (break into short series) so I'm
not guessing...
