From: Nicholas Kazlauskas <nicholas.kazlaus...@amd.com>
[Why]
Surface scaling info updates can affect bandwidth and blocks. We need
to be checking these with global validation to avoid underflow or
corruption.
[How]
Drop the state->allow_modeset early exit in
dm_determine_update_type_for_commit. Most of those should be considered
fast now anyway.
Fill in scaling info and it to the surface update in atomic
check.
