Merge tag 'usb-3.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull more USB fixes from Greg Kroah-Hartman:
"Here are some more USB fixes for the 3.8-rc4 tree.
Some gadget driver fixes, and finally resolved the ehci-mxc driver
build issues (it's just some code moving around and being deleted)."
* tag 'usb-3.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
USB: EHCI: fix build error in ehci-mxc
USB: EHCI: add a name for the platform-private field
USB: EHCI: fix incorrect configuration test
USB: EHCI: Move definition of EHCI_STATS to ehci.h
USB: UHCI: fix IRQ race during initialization
usb: gadget: FunctionFS: Fix missing braces in parse_opts
usb: dwc3: gadget: fix ep->maxburst for ep0
ARM: i.MX clock: Change the connection-id for fsl-usb2-udc
usb: gadget: fsl_mxc_udc: replace MX35_IO_ADDRESS to ioremap
usb: gadget: fsl-mxc-udc: replace cpu_is_xxx() with platform_device_id
usb: musb: cppi_dma: drop '__init' annotation
