Merge tag 'usb-3.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "Here are a number of USB fixes for reported issues for 3.14-rc4

  The majority of these are for USB gadget, phy, and musb driver issues.
  And there's a few new device ids thrown in for good measure"

* tag 'usb-3.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
  usb: chipidea: need to mask when writting endptflush and endptprime
  usb: musb: correct use of schedule_delayed_work()
  usb: phy: msm: fix compilation errors when !CONFIG_PM_SLEEP
  usb: gadget: fix NULL pointer dereference
  usb: gadget: printer: using gadget_is_otg to check otg support at runtime
  phy: let phy_provider_register be the last step in registering PHY
  phy-core: Don't allow building phy-core as a module
  phy-core: Don't propagate -ENOSUPP from phy_pm_runtime_get_sync to caller
  phy-core: phy_get: Leave error logging to the caller
  phy,phy-bcm-kona-usb2.c: Add dependency on HAS_IOMEM
  usb: musb: correct use of schedule_delayed_work()
  usb: musb: do not sleep in atomic context
  USB: serial: option: blacklist interface 4 for Cinterion PHS8 and PXS8
  USB: EHCI: add delay during suspend to prevent erroneous wakeups
  usb: gadget: bcm63xx_udc: fix build failure on DMA channel code
  usb: musb: do not sleep in atomic context
  usb: gadget: s3c2410_udc: Fix build error
  usb: musb: core: Fix remote-wakeup resume
  usb: musb: host: Fix SuperSpeed hub enumeration
  usb: musb: fix obex in g_nokia.ko causing kernel panic
