Merge tag 'usb-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH: "Here are some remaining USB fixes for 4.13-rc1. They were originally scheduled for 4.12-final, but I didn't send them to you in time. Because of that, they were in a separate branch from the larger USB set of patches, so here they are in a separate pull request. Nothing major here a all, just three small patches: - some usb-serial new device ids - xhci bugfix for some crazy AMD hardware All of these have been in linux-next for a long time with no reported issues" * tag 'usb-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: xhci: Limit USB2 port wake support for AMD Promontory hosts USB: serial: qcserial: new Sierra Wireless EM7305 device ID USB: serial: option: add two Longcheer device ids
