Merge tag 'usb-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY driver updates from Greg KH: "Here is the large USB and PHY driver update for 4.14-rc1. Not all that exciting, a few new PHY drivers, the usual mess of gadget driver updates and fixes, and of course, xhci updates to try to tame that beast. A number of usb-serial updates and other small fixes all over the USB driver tree are in here as well. Full details are in the shortlog. All of these have been in linux-next for a while with no reported issues" * tag 'usb-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (171 commits) usbip: vhci-hcd: make vhci_hc_driver const usb: phy: Avoid unchecked dereference warning usb: imx21-hcd: make imx21_hc_driver const usb: host: make ehci_fsl_overrides const and __initconst dt-bindings: mt8173-mtu3: add generic compatible and rename file dt-bindings: mt8173-xhci: add generic compatible and rename file usb: xhci-mtk: add generic compatible string usbip: auto retry for concurrent attach USB: serial: option: simplify 3 D-Link device entries USB: serial: option: add support for D-Link DWM-157 C1 usb: core: usbport: fix "BUG: key not in .data" when lockdep is enabled usb: chipidea: usb2: check memory allocation failure usb: Add device quirk for Logitech HD Pro Webcam C920-C usb: misc: lvstest: add entry to place port in compliance mode usb: xhci: Support enabling of compliance mode for xhci 1.1 usb:xhci:Fix regression when ATI chipsets detected usb: quirks: add delay init quirk for Corsair Strafe RGB keyboard usb: gadget: make snd_pcm_hardware const usb: common: use of_property_read_bool() USB: core: constify vm_operations_struct ...
