[PATCH 0/4] Use -Werror by default and fix compilation warnings

[Rodrigo Siqueira]

We have an internal CI in the display team that uses a stable version of
amd-staging-drm-next to run a set of tests (from compilation to IGT);
usually, we have to create this stable version manually. We are trying
to automate this process, but we are getting failures because we compile
display code with the flag -Werror, which means we cannot ignore
warnings in amd-staging-drm-next. In this patchset, I propose enabling
-Werror flag by default in amdgpu to make it a little bit harder to
ignore warning messages. The first patch of this series updates amdgpu
Makefile, and the other patches fix warning issues in amdgpu.

I tested this series with DCN, DCN disabled, and with `allmodconfig`; I
did not have any compilation issue.

Thanks
Siqueira
