Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86
Pull x86 platform driver updates from Matthew Garrett:
"Support for the new keyboard features on the Thinkpad Carbon, a bunch
of updates for the Sony and Toshiba drivers, a new driver for upcoming
Alienware hardware and a few misc fixes. There's a couple of patches
that got Acked today but aren't invasive, so I'll send a further PR
for them next week"
