Subject: drm/amd/display: Set plane update flags for all planes in reset
Git-commit: 21431f70f6014f81b0d118ff4fcee12b00b9dd70
Patch-mainline: v5.16-rc3
References: git-fixes
Alt-commit: 6984fa418b8efde7662af151bae4b8dc66e65fcf
[Why]
We're only setting the flags on stream[0]'s planes so this logic fails
if we have more than one stream in the state.
This can cause a page flip timeout with multiple displays in the
configuration.
[How]
Index into the stream_status array using the stream index - it's a 1:1
mapping.
