Use SPDX license header instead of the full text?

I don't know much about the actual contents, I'll leave that part to
others.

Seems that you are dropping const in a number of places where I thought
you could perhaps retain it.

Also in drivers/gpu/drm/i915/intel_gvt_mmio_table.c:

#include "gvt.h" 

looks bad. It should be "gvt/gvt.h". I realize you can do that because
gvt/Makefile has:

ccflags-y += -I $(srctree)/$(src) -I $(srctree)/$(src)/$(GVT_DIR)/

which I think should be removed.

I sent patches fixing this to give you an idea. No need to queue them
first, I can rebase them later. But please make sure this builds without
the ccflags.


BR,
Jani.
