Merge branch 'usb-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb-2.6
* 'usb-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb-2.6: (205 commits) USB: EHCI: Remove SPARC_LEON {read,write}_be definitions from ehci.h USB: UHCI: Support big endian GRUSBHC HC sparc: add {read,write}*_be routines USB: UHCI: Add support for big endian descriptors USB: UHCI: Use ACCESS_ONCE rather than using a full compiler barrier USB: UHCI: Add support for big endian mmio usb-storage: Correct adjust_quirks to include latest flags usb/isp1760: Fix possible unlink problems usb/isp1760: Move function isp1760_endpoint_disable() within file. USB: remove remaining usages of hcd->state from usbcore and fix regression usb: musb: ux500: add configuration and build options for ux500 dma usb: musb: ux500: add dma glue layer for ux500 usb: musb: ux500: add dma name for ux500 usb: musb: ux500: add ux500 specific code for gadget side usb: musb: fix compile error usb-storage: fix up the unusual_realtek device list USB: gadget: f_audio: Fix invalid dereference of initdata EHCI: don't rescan interrupt QHs needlessly OHCI: fix regression caused by nVidia shutdown workaround USB: OTG: msm: Free VCCCX regulator even if we can't set the voltage ...
