Description

In the Linux kernel the following vulnerability has been resolved:

drm/amd/display: Fix null check for pipe_ctx->plane_state in resource_build_scaling_params

Null pointer dereference issue could occur when pipe_ctx->plane_state is null. The fix adds a check to ensure ‘pipe_ctx->plane_state’ is not null before accessing. This prevents a null pointer dereference.

Found by code review.
