Hi All,

Sorry for the delay in replying, it's been a very long time since I used
patch and I'm rusty :).

I couldn't quite get "make install" to work but I installed by hand and
things look good.

"make install" gave the following message:

===>   Registering installation for gpu-firmware-kmod-g20180206_1
pkg-static: Unable to access file
/usr/ports/graphics/gpu-firmware-kmod/work/stage/boot/modules/i915_bxt_huc_ver01_07_1398_bin.ko:No
such file or directory

plus two more for the other long names.

I used the "make install" to build and stage them, then copied in the
modules by hand and removed the old ones.

It all runs, the graphics look good, and I can run:

   xldxref -d /boot/modules

without any erorrs.

Thanks for the patch - in fact, thanks to all involved for all the work
on the i915 driver!
