Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86

Pull x86 platform driver updates from Matthew Garrett:
 "Some significant updates to samsung-laptop, additional hardware
  support for Toshibas, misc updates to various hardware and a new
  backlight driver for some Apple machines."

Fix up trivial conflicts: geode Geos update happening next to net5501
support, and MSIC thermal platform support added twice.
