Merge tag 'usb-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH: "Here is the big USB and PHY driver update for 4.16-rc1. Along with the normally expected XHCI, MUSB, and Gadget driver patches, there are some PHY driver fixes, license cleanups, sysfs attribute cleanups, usbip changes, and a raft of other smaller fixes and additions. Full details are in the shortlog. All of these have been in the linux-next tree for a long time with no reported issues" * tag 'usb-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (137 commits) USB: serial: pl2303: new device id for Chilitag USB: misc: fix up some remaining DEVICE_ATTR() usages USB: musb: fix up one odd DEVICE_ATTR() usage USB: atm: fix up some remaining DEVICE_ATTR() usage USB: move many drivers to use DEVICE_ATTR_WO USB: move many drivers to use DEVICE_ATTR_RO USB: move many drivers to use DEVICE_ATTR_RW USB: misc: chaoskey: Use true and false for boolean values USB: storage: remove old wording about how to submit a change USB: storage: remove invalid URL from drivers usb: ehci-omap: don't complain on -EPROBE_DEFER when no PHY found usbip: list: don't list devices attached to vhci_hcd usbip: prevent bind loops on devices attached to vhci_hcd USB: serial: remove redundant initializations of 'mos_parport' usb/gadget: Fix "high bandwidth" check in usb_gadget_ep_match_desc() usb: gadget: compress return logic into one line usbip: vhci_hcd: update 'status' file header and format USB: serial: simple: add Motorola Tetra driver CDC-ACM: apply quirk for card reader usb: option: Add support for FS040U modem ...
