Hi Stefan,

For this particular patch, I simply cherry-picked the orignal version
of the driver in the github directory.  It's a 100% original copy of
the initial version.

So any grips/complaints should be sent to dave.stevenson at raspberrypi.or
g.

Or better yet, if the driver is accepted then you can contribute to
making it better.
