On the other hand, in usbhid driver we do a lot of USB-specific lower-level things anyway, so it's technically more-or-less OK to apply the quirk there as well (and that's why I have accepted it back then). -- Jiri Kosina SUSE Labs, Novell Inc. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
