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/toshiba_acpi.c between commit f5f4fd451634
("backlight: initialize struct backlight_properties properly") from
Linus' tree and commit 7d307fbdefbf ("toshiba_acpi: Only register
backlight device when interface is read/write") from the drivers-x86 tree.

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