Seems like this is a false positive for GCC versions pre-12, because I'm
not seeing this warning on GCC 12.2.
However, we can fix this for older GCC versions with the following:
diff --git a/drivers/gpu/drm/amd/display/dc/dc_stream.h
b/drivers/gpu/drm/amd/display/dc/dc_stream.h
index 9e6025c98db9..67fede4bf248 100644
--- a/drivers/gpu/drm/amd/display/dc/dc_stream.h
+++ b/drivers/gpu/drm/amd/display/dc/dc_stream.h
