[Intel-gfx] Fixing i915/opregion issues with firmware which lists more then 8 output devices

[tasev.stefanoska]

Hi Jani

Following the thread :
http://www.spinics.net/lists/intel-gfx/msg92832.html

I tried to build a kernel with the patch 
https://patchwork.freedesktop.org/series/4783/ but did not succeed.

What i did is: git clone git https://cgit.freedesktop.org/~jani/drm/
then i looked into the intel_opregion.c file but it doesn't seems that 
[v4] drm/i915/opregion: update cadl based on actually active outputs
[v4] drm/i915: make i915 the source of acpi device ids for _DOD
are included.

I tried to apply the patches manually, but after that, building the 
kernel fails with errors. What is the right way to test the patches?

Thanks,
Nikola
