All drivers in staging need a TODO file that lists what is needed to be done to it in order to get it out of staging. Why not just submit it to the "real" part of the kernel? thanks, greg k-h _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
