Merge tag 'usb-4.7-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB and PHY fixes from Greg KH: "Here are a number of small USB and PHY driver fixes for 4.7-rc6. Nothing major here, all are described in the shortlog below. All have been in linux-next with no reported issues" * tag 'usb-4.7-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: USB: don't free bandwidth_mutex too early USB: EHCI: declare hostpc register as zero-length array phy-sun4i-usb: Fix irq free conditions to match request conditions phy: bcm-ns-usb2: checking the wrong variable phy-sun4i-usb: fix missing __iomem * phy: phy-sun4i-usb: Fix optional gpios failing probe phy: rockchip-dp: fix return value check in rockchip_dp_phy_probe() phy: rcar-gen3-usb2: fix unexpected repeat interrupts of VBUS change usb: common: otg-fsm: add license to usb-otg-fsm
