Merge tag 'staging-3.5-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging 



Pull staging tree fixes from Greg Kroah-Hartman:
 "Here are a number of small fixes for the drivers/staging tree, as well
  as iio and pstore drivers (which came from the staging tree in the
  3.5-rc1 merge).  All of these are tiny, but resolve issues that people
  have been reporting.

  There's also a documentation update to reflect what the iio drivers
  really are doing, which is good to get straightened out.
