* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb-2.6:
  Revert "USB: Correct Makefile to make isp1760 buildable"
  usb-serial: fix crash when sub-driver updates firmware
  USB: isp1760: urb_dequeue doesn't always find the urbs
  USB: Yet another Conexant Clone to add to cdc-acm.c
  USB: atmel_usb_udc: Use kzalloc() to allocate ep structures
  USB: atmel-usba-udc : fix control out requests.
