Oops, my bad. I've sent a patch to the linux-media mailing list that should be applied on top of that one. It seems the v4l maintainer forgot to fold the two patches together (or even apply the second one). I've reminded him today and told him it's urgent, I hope that will go in 2.6.31. The patch can be found at http://article.gmane.org/gmane.linux.drivers.video- input-infrastructure/8265/ Regards, Laurent Pinchart _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
