[AMD Official Use Only - Internal Distribution Only] Hi Arnd, I have all the patches ready and I have tested them with the feature/platform I'm working on and Bindu helped to test the 32bit build. I'm in process of submitting the latest change. Thanks, Vladimir.

I found two more instances: >>> referenced by dcn20_optc.c >>> gpu/drm/amd/display/dc/dcn20/dcn20_optc.o:(optc2_align_vblanks) in archive drivers/built-in.a >>> referenced by dcn10_hw_sequencer.c >>> gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.o:(reduceSizeAndFraction) in archive drivers/built-in.a I have patches for both, but will let the randconfig build box keep working on it over night to see if there are any others. Let me know if you want a combined patch or one per file once there are no more regressions.
