Yes, that's all I care about in staging, but as I stated, I don't maintain drivers/staging/media/ that area is under Mauro's control (MAINTAINERS even says this), and I'm a bit leery of going against the wishes of an existing subsystem maintainer for adding staging drivers that tie into their subsystem. So if you get Mauro's approval, I'll be glad to queue it up. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
