Yeah, I did that in a previous version, but Ville wanted it to be int.
Personally I don't really care as long as I remember to use int when
I have a loop that counts down to zero, which has bitten me before.
So based on my experience maybe I should always use plain int in loop
indices, too avoid that rare count down case where I continue to use
unsigned int for the loop index, me being a limited human being :-)

Use drm_framebuffer_print_info() to print framebuffer info in
drm_atomic_plane_print_state(). This will give optional GEM info as well.

This will happily return a non-const pointer to the drm_gem_cma_object based
on a const pointer to the contained drm_gem_object, thus creating const-safety
problems.
There was an attempt to fix the problem in the container_of() macro itself
(see https://lkml.org/lkml/2017/5/19/381) but the patch seems to have fallen
through the cracks. It would require turning this inline function into a
macro.
I don't think we need to wait for the container_of() patch to land, but it
would be useful to turn the inline function into a macro already to
automatically benefit from the change, instead of introducting a const-safety
problem that we will all forget about until it breaks something in the future.

There is a new core debugfs file that prints fb/gem info:
<debugfs>/dri/<n>/framebuffer
Use drm_gem_cma_print_info() to provide info to that output instead
of using drm_fb_cma_debugfs_show().

BTW "layers" seems like a somewhat confusing term to use here. I believe
layers mean something different in GL, so we probably shouldn't use that
name here.
The current name used in the code is "plane". But that too is rather
confusing on account of drm_plane. IIRC in the past I've proposed that
we should s/plane/color_plane/ when talking about the planes of a
framebuffer.

There is a new core debugfs file that prints fb/gem info:
<debugfs>/dri/<n>/framebuffer
Use drm_gem_cma_print_info() to provide info to that output instead
of using drm_fb_cma_debugfs_show().

I'm going to assume that you are going to carry the whole series through
