There will be a couple of other sh-sci patches for the next kernel version that should then go through Simon's tree as well. I will make sure to post them for review on the linux-serial list and CC you to get your ack (from what I've been told the ARM SoC maintainer usually dislike driver patches going through their tree without the driver subsystem maintainer ack). > Acked-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Thank you. -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
