  driver-core: fix new kernel-doc warning in base/platform.c (2013-07-16 22:43:50 -0700)

Driver core patches for 3.11-rc2

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.
