Ok, maybe I've had too much coffee this morning, but I don't see any new global variables being added in your patch. I see a static one (the intel structure), but nothing "global".

All of this should be in the 1/1 patch description as well. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
