Currently it is deleted in linux-next due to a lack of development. I see you have some cleanup patches, but I can't apply them unless you get the non-staging patches accepted. If I bring the driver back from deletion, will you work to fix it up and get it merged into mainline? What's the word on the non-staging patches in this series being accepted? thanks, greg k-h _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
