Merge tag 'staging-3.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging driver fixes from Greg KH:
 "Here are a few staging driver fixes for issues that have been reported
  for 3.15-rc2.

  Also dominating the diffstat for the pull request is the removal of
  the rtl8187se driver.  It's no longer needed in staging as a "real"
  driver for this hardware is now merged in the tree in the "correct"
  location in drivers/net/

  All of these patches have been tested in linux-next"
