Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb-2.6

* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb-2.6: (141 commits)
  USB: mct_u232: fix broken close
  USB: gadget: amd5536udc.c: fix error path
  USB: imx21-hcd - fix off by one resource size calculation
  usb: gadget: fix Kconfig warning
  usb: r8a66597-udc: Add processing when USB was removed.
  mxc_udc: add workaround for ENGcm09152 for i.MX35
  USB: ftdi_sio: add device ids for ScienceScope
  USB: musb: AM35x: Workaround for fifo read issue
  USB: musb: add musb support for AM35x
  USB: AM35x: Add musb support
  usb: Fix linker errors with CONFIG_PM=n
  USB: ohci-sh - use resource_size instead of defining its own resource_len macro
  USB: isp1362-hcd - use resource_size instead of defining its own resource_len macro
  USB: isp116x-hcd - use resource_size instead of defining its own resource_len macro
  USB: xhci: Fix compile error when CONFIG_PM=n
  USB: accept some invalid ep0-maxpacket values
  USB: xHCI: PCI power management implementation
  USB: xHCI: bus power management implementation
  USB: xHCI: port remote wakeup implementation
  USB: xHCI: port power management implementation
  ...

Manually fix up (non-data) conflict: the SCSI merge gad renamed the
'hw_sector_size' member to 'physical_block_size', and the USB tree
brought a new use of it.
