linux-next: manual merge of the drivers-x86 tree with Linus' tree

[Stephen Rothwell]

Hi Matthew,

Today's linux-next merge of the drivers-x86 tree got a conflict in
drivers/platform/x86/sony-laptop.c between commit bb7ca747f8d6
("backlight: add backlight type") from Linus' tree and commit
8a217a64f01c ("sony-laptop: implement new backlight control method") from
the drivers-x86 tree.

I fixed it up (see below) and can carry the fix as necessary.
