Merge branch 'for-linus' of git://git.o-hand.com/linux-rpurdie-backlight
* 'for-linus' of git://git.o-hand.com/linux-rpurdie-backlight:
backlight: mbp_nvidia_bl - add two more MacBookPro variants
backlight: Pass device through notify callback in the pwm driver
backlight: PTR_ERR return of wrong pointer in cr_backlight_probe()
backlight: Constify struct backlight_ops
backlight/thinkpad-acpi: issue backlight class events
Fix up trivial conflicts in thinkpad-acpi support (backlight support
already merged earlier).
