[PATCH 2/2] drm/amd/display: ZERO_OR_NULL_PTR Macro overdetection

[luoqing]

From: luoqing <luoq...@kylinos.cn>

sizeof(xx) these variable values' return values cannot be 0.
For memory allocation requests of non-zero length,
there is no need to check other return values;
it is sufficient to only verify that it is not null.
