Hi Jonathan,
I noticed that, another commit for this driver has been accepted here [1],
which will affect some patches of this series that I am adding. It's not
difficult at all to apply changes to my patches with respect to this new
addition. Should I move on with a v6 without taking into consideration
this change, and if everything is finally approved, I can send
later a v7 with only the changes needed for this new commit?
Cheers,
Vasilis
