This series: * Cleans up i915's DPCD backlight code a little bit * Extracts i915's DPCD backlight code into a set of shared DRM helpers * Starts using those helpers in nouveau to add support to nouveau for DPCD backlight control
v2 series-wide changes: * Rebase v3 series-wide changes: * Split up the changes to intel's backlight code into separate patches v4 series-wide changes: * Don't forget to actually include the patch that starts using these helpers in nouveau v5 series-wide changes: * Rebase * Use new drm_dbg_*() logging helpers
