Ah right, my bad you really need that third patch, this one to be specific:

https://git.kernel.org/cgit/linux/kernel/git/rafael/linux-pm.git/commit/drivers/acpi/video.c?h=linux-next&id=ff92cfe7cbc05c6c62f5b06c7d9090f4c853cd51

And you need to apply them in reverse order as I gave them to you, so in this
order:
