Currently, there are quite a number of issues that are quite easy for
the CI to catch, that slip through the cracks. Among them, there are
unused variable and indentation issues. Also, we should consider all
warnings to be compile errors, since the community will eventually end
up complaining about them. So, enable -Werror, -Wunused and
-Wmisleading-indentation for all kernel builds.

Care to enable this for the rest of amdgpu as well? Or send out an
additional patch to do that? Either way:

As far as I can tell, if `CONFIG_DRM_AMD_DC` is set it will run these
checks on at least the base driver code.
