The commit message of this change should maybe have been clearer, but the warning is expected. The bootloader fixes the DT before passing it on to Linux by completing the other direction of link if eDP is enabled. How do we want to handle this? If you totally dislike the warning I can get around it by not adding the link and adding some more complexity to the bootloader, but given the choice I would like to keep the incomplete link in the Linux DT and keep bootloader complexity down.
