Lee, I believe this series is ready for merging now ?  I've reviewed
patches 1-2 + 5 and Jacek has reviewed patches 3 + 4.

Patch 5 also has an Acked-by from Sebastian for merging it together
with the rest of the series.

Can you merge patches 1-5 ?

Patch 6 just changes the value of a device-property (the default-trigger
string) and I can merge that through the pdx86 tree independent of
patches 1-5.

Regards,

Hans
