Thanks and this patch is now merged to amd-staging-drm-next, but I found 
it causes *some* compiler to fail.

I'd like to test whether the below change is able to fix both issues.

-static const struct stream_encoder_funcs dce110_an_str_enc_funcs = {};
+static const struct stream_encoder_funcs dce110_an_str_enc_funcs = {
+       .dp_set_stream_attribute = NULL,
+};

However, I could not reproduce ""positional initialization of field in 
'struct' declared 'designated_init' attribute" in my local setup, with 
either gcc or clang and "CONFIG_RANDSTRUCT=y"

Can someone try the above changes for me? really appreciate it. I will 
create a patch if it works.
