Merge tag 'usb-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB patches from Greg Kroah-Hartman: "Here's the big set of USB patches for 3.8-rc1. Lots of USB host driver cleanups in here, and a bit of a reorg of the EHCI driver to make it easier for the different EHCI platform drivers to all work together nicer, which was a reduction in overall code. We also deleted some unused firmware files, and got rid of the very old file_storage usb gadget driver that had been broken for a long time. This means we ended up removing way more code than added, always a nice thing to see: 310 files changed, 3028 insertions(+), 10754 deletions(-) Other than that, the usual set of new device ids, driver fixes, gadget driver and controller updates and the like. All of these have been in the linux-next tree for a number of weeks.
