Merge tag 'staging-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging tree update from Greg KH:
 "Here's the large staging tree merge for 3.11-rc1

  Huge thing here is the Lustre client code.  Unfortunatly, due to it
  not building properly on a wide variety of different architectures
  (this was production code???), it is currently disabled from the build
  so as to not annoy people.

  Other than Lustre, there are loads of comedi patches, working to clean
  up that subsystem, iio updates and new drivers, and a load of cleanups
  from the OPW applicants in their quest to get a summer internship.

  All of these have been in the linux-next releases for a while (hence
  the Lustre code being disabled)"

Fixed up trivial conflict in drivers/staging/serqt_usb2/serqt_usb2.c due
to independent renamings in the staging driver cleanup and the USB
tree..
