Your remarks is correct. All your remarks were. Problem currently is 
that I'm not assigned to a project related to the davinci so I cannot 
spend time to fix and port it (the actual platform still runs 2.6.37).

Feel free to adap my patch or comments and commit. Or wait a few weeks 
for when I have a sponsor to split and update the patch.
