Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers…

…-x86

Pull x86 platform driver updates from Matthew Garrett:
 "A moderate diffstat, but it's almost entirely just moving the
  chromebook driver into its own directory in order to ease ARM support,
  adding back rfkill support to the one Dell laptop model where it's
  expected to work, updates to the Intel IPC driver for hardware I've
  never actually seen and the usual set of small fixes"

[ This actually came in before the merge window closed, and I had just
  missed it because it didn't match my git pull email pattern.  - Linus ]
