### Description

In the Linux kernel, the following vulnerability has been resolved:drm/amd/display: Add null check for pipe_ctx->plane_state in dcn20_program_pipeThis commit addresses a null pointer dereference issue in the`dcn20_program_pipe` function. The issue could occur when`pipe_ctx->plane_state` is null.The fix adds a check to ensure `pipe_ctx->plane_state` is not nullbefore accessing. This prevents a null pointer dereference.Reported by smatch:drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn20/dcn20_hwseq.c:1925 dcn20_program_pipe() error: we previously assumed 'pipe_ctx->plane_state' could be null (see line 1877)
