[PATCH 4.9 091/145] drm/i915: fix intel_backlight_device_register declaration

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

commit ac29fc66855b79c2960c63a4a66952d5b721d698 upstream.

The alternative intel_backlight_device_register() definition apparently
never got used, but I have now run into a case of i915 being compiled
without CONFIG_BACKLIGHT_CLASS_DEVICE, resulting in a number of
identical warnings:

drivers/gpu/drm/i915/intel_drv.h:1739:12: error: 
'intel_backlight_device_register' defined but not used [-Werror=unused-function]

This marks the function as 'inline', which was surely the original
intention here.

registration")
