Merge tag 'usb-4.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb 

Pull USB / PHY driver fixes from Greg KH:
 "Here are two small sets of patches, both from subsystem trees, USB
  gadget and PHY drivers.

  Full details are in the shortlog, and they have all been in linux-next
  for a while (before I merged them to the USB tree)"

* tag 'usb-4.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
  usb: gadget: f_fs: Fix use-after-free
  usb: dwc3: gadget: Fix suspend/resume during device mode
  usb: dwc3: fix memory leak of dwc->regset
  usb: dwc3: core: fix PHY handling during suspend
  usb: dwc3: omap: fix up error path on probe()
  usb: gadget: composite: Clear reserved fields of SSP Dev Cap
  phy: rockchip-emmc: adapt binding to specifiy register offset and length
  phy: rockchip-emmc: should be a child device of the GRF
  phy: rockchip-dp: should be a child device of the GRF
