Austin Zheng a0c50c9f9c drm/amd/display: Call FP Protect Before Mode Programming/Mode Support ...

[ Upstream commit eba692ca3a ]

[Why]
Memory allocation occurs within dml21_validate() for adding phantom planes.
May cause kernel to be tainted due to usage of FP Start.

[How]
Move FP start from dml21_validate to before mode programming/mode support.
Calculations requiring floating point are all done within mode programming
or mode support.
