I find many of your subjects has "." at last, it doesn't need, I fix them this time. Thanks for your work for otg fsm for chipidea, I will send them to Greg. -- Best Regards, Peter Chen -- 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
