From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> This series tries to fix the initial backlight setup on VLV/CHV so that we read out the hardware state from the correct pipe's BLC registers. Makes for a better experience on BSW where the BIOS always uses pipe B for the eDP port. I also noticed some weirdness with systemd due to the early backlight device registration, so I went ahead and moved that to occur after the modeset init has finished. That should fix the race between our state readout and userspace backlight frobbery.
