It would make sense to keep the comment around, but maybe in a more dense format without all paramters explained. Maybe just a simple: /* * Checks that a desired plane update is valid. * Returns 0 if update appears valid, error code on failure */ Sam _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
