We are moving to a dual license GPL/X11:
http://thread.gmane.org/gmane.linux.ports.arm.kernel/380065

Could you consider to use it too?
The file you based on will be converted, all the author of this
file already have given their acked-by.


In meantime, I will review the content of your patch.

Thanks,

Gregory
