As "dcn3_15_soc" and "dcn3_16_soc" are of type "struct
_vcs_dpi_soc_bounding_box_st", change their types accordingly.

I can see that indeed this type change sense for those variables, but
isn't a bit strange that the type was wrong in the first place? I wonder
if this variable is even used, given that it would very likely throw a
compiler error when using the wrong type and trying to access struct
members that aren't defined.

A compilation error would be thrown if either
"dc/dcn315/dcn315_resource.h" or "dc/dcn316/dcn316_resource.h" were
included in the files where "dcn3_15_soc" and "dcn3_16_soc" are
initialized. Since they are not included, the wrong variable type error
is not shown.
To solve the sparse warning in the second patch of this series, those
variables need to be declared first, but they are already declared,
we're only missing the headers. If I only add the headers, then those
variables will be seen, and I get the expected incompatible variables
types error. So, fixing the types here is a preliminary work for the
next patch.

I see that this fix (right above) comes from another warning not listed
in the commit message. Can you explicit it there or split it in
another commit if possible?
Also, clk_mgr/dcn21/rn_clk_mgr.c includes clk_mgr_internal.h and
rn_clk_mgr.h; I wonder if a cleaner solution is to remove the
`#include clk_mgr_internal.h` from rn_clk_mgr.c too.
The remaining changes seems correct to me.
Thanks,
Melissa

Hi Magali,
Thanks for inspecting it. What you say makes sense, but Andr? pointed
out something that makes sense to me too.
As fas as I checked, dcn3_15_soc and dcn16_soc is not used outside their
respective FPU files. Maybe the proper solution is removing those
declarations (and make the struct static). Can you take a look at it?

Melissa

Hi, Melissa. Thank you for the suggestion!
My sole reason not to make those structs static was to keep some sort of
consistency with the rest of the dcn*_resource.h files, since that is
where all the other structs are first declared. I'm not sure, though, if
that's a good enough reason not to turn these variables into static. Let
me know what you think.

And what happens if you just drop this declaration? It still not clear
to me why this belongs to this header, giving that AFAIK this var is
only used at drivers/gpu/drm/amd/display/dc/dml/dcn31/dcn31_fpu.c
Note that this kind of information you explained to me would be very
useful if you had included it in a cover letter to add more context for
your patches :)

I don't see any other file using dcn3_15_soc, it's only in dcn30_fpu, so
better make it static. Also, I see that doing this will ring a bell
for some misuse of the struct outside FPU protection, in the future.
With those points addressed, you can add in the next version:
