acpi_video_dmi_demote_vendor() is going away as part of the cleanup of the code for determinging which backlight class driver(s) to register. The call to acpi_video_dmi_demote_vendor() was meant to undo the call to acpi_video_dmi_promote_vendor() when the gmux device is removed, this is questionable though since the promote call sets a flag, not a counter, so the demote call may undo a promoto done elsewhere. Moreover in practice this is a nop since the gmux device is never removed, and the flag is only checked when acpi/video.ko gets loaded, so even if the user manually removes apple-gmux the demote call is still a nop as video.ko will already have loaded by this time. Also note that none of the other users of acpi_video_dmi_promote_vendor() use acpi_video_dmi_demote_vendor(). If we ever encounter a system with a gmux where the acpi-video interface should be used, then the proper fix would be to dmi-blacklist the gmux driver on that system.
