    Merge tag 'driver-core-3.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
    
    Pull driver core patches from Greg KH:
     "Here are some driver core patches for 3.11-rc2.  They aren't really
      bugfixes, but a bunch of new helper macros for drivers to properly
      create attribute groups, which drivers and subsystems need to fix up a
      ton of race issues with incorrectly creating sysfs files (binary and
      normal) after userspace has been told that the device is present.
    
      Also here is the ability to create binary files as attribute groups,
      to solve that race condition, which was impossible to do before this,
      so that's my fault the drivers were broken.
    
      The majority of the .c changes is indenting and moving code around a
      bit.  It affects no existing code, but allows the large backlog of 70+
      patches that I already have created to start flowing into the
      different subtrees, instead of having to live in my driver-core tree,
      causing merge nightmares in linux-next for the next few months.
    
      These were finalized too late for the -rc1 merge window, which is why
      they were didn't make that pull request, testing and review from
      others didn't happen until a few weeks ago, and then there's the whole
      distraction of the past few days, which prevented these from getting
      to you sooner, sorry about that.
    
      Oh, and there's a bugfix for the documentation build warning in here
      as well.  All of these have been in linux-next this week, with no
      reported problems"
