They look like they could be changed to min().
It is even likely the header gets pulled in somewhere.

I'm not sure about the ones in drivers/gpu/drm/amd/display/*..*/*.c, but it
wouldn't surprise me if that code doesn't use any standard kernel headers.
Isn't that also the code that manages to pass 42 integer parameters
to functions?
