a few general notes:

- please use my arnd at arndb.de address on patch submissions, not the linaro
  address.

- for the email subject lines, have a look at what the typical style
  is for the file. "overlay:" is not a good name here because it's not
  unique to the driver, so better use "drm/nouveau", which will also
  get the attention of the right people.

- please drop the "fix:" prefix in the subject.
