Hi all,
This series resolves a couple instances of -Wframe-larger-than from
the new display code that appear with newer versions of clang along
without another inconsistency I noticed while fixing this, which have
been accounted for with the $(frame_warn_flag) variable.

Hi Greg and Sasha,
Please apply upstream commit 5b750b22530f ("drm/amd/display: Increase

is needed to avoid instances of -Wframe-larger-than in allmodconfig,
which has -Werror enabled. It applies cleanly for me and it is
