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

Browse Source 
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.

---help---
This driver provides support for extra features of ACPI-compatible
ASUS laptops. As some of Medion laptops are made by ASUS, it may also
support some Medion laptops (such as 9675 for example). It makes all
the extra buttons generate standard ACPI events that go through
/proc/acpi/events, and (on some models) adds support for changing the
display brightness and output, switching the LCD backlight on and off,
and most importantly, allows you to blink those fancy LEDs intended
for reporting mail and wireless status.
Note: display switching code is currently considered EXPERIMENTAL,
toying with these values may even lock your machine.
All settings are changed via /proc/acpi/asus directory entries. Owner
and group for these entries can be set with asus_uid and asus_gid
parameters.
More information and a userspace daemon for handling the extra buttons
at <http://acpi4asus.sf.net>.
If you have an ACPI-compatible ASUS laptop, say Y or M here. This
driver is still under development, so if your laptop is unsupported or
something works not quite as expected, please use the mailing list
available on the above page (acpi4asus-user@lists.sourceforge.net).
NOTE: This driver is deprecated and will probably be removed soon,
use asus-laptop instead.
