Pull USB fixes from Greg KH:
 "Here are a few USB fixes for things that have people have reported
  issues with recently"

* tag 'usb-3.13-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
  usb: ohci-at91: fix irq and iomem resource retrieval
  usb: phy: fix driver dependencies
  phy: kconfig: add depends on "USB_PHY" to OMAP_USB2 and TWL4030_USB
  drivers: phy: tweaks to phy_create()
  drivers: phy: Fix memory leak
  xhci: Limit the spurious wakeup fix only to HP machines
  usb: chipidea: fix nobody cared IRQ when booting with host role
  usb: chipidea: host: Only disable the vbus regulator if it is not NULL
  usb: serial: zte_ev: move support for ZTE AC2726 from zte_ev back to option
  usb: cdc-wdm: manage_power should always set needs_remote_wakeup
  usb: phy-tegra-usb.c: wrong pointer check for remap UTMI
  usb: phy: twl6030-usb: signedness bug in twl6030_readb()
  usb: dwc3: power off usb phy in error path
  usb: dwc3: invoke phy_resume after phy_init
