As you found, there was a trivial merge conflict with "usb: dwc2: reset dwc2 core before dwc2_get_hwparams()" and you resolved it in the same way that I resolved it locally. I'm not sure tags like Tested-by or Reviewed-by make sense for patches that I authored and/or have Signed-off-by, but just noting that I'm OK with them as you've reposted (thanks!) I picked all the other patches locally to my 3.14 too and am testing. So far so good. I've got a farm of 5 devices doing reboot tests overnight. On each bootup it will confirm that a USB based Ethernet adapter on one of the two ports is at least sane enough to get SSH connections and that the device never crashes. I'll send review feedback and tested-by for each patch (other than the gadget ones, which I applied mostly to avoid merge conflicts) tomorrow morning on the conclusion of the boot test. -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
