The issue could occur\nwhen `head_pipe` is null.\n\nThe fix adds a check to ensure `head_pipe` is not null before asserting\nit. If `head_pipe` is null, the function returns NULL to prevent a\npotential null pointer dereference.\n\nReported by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn201/dcn201_resource.c:1016 dcn201_acquire_free_pipe_for_layer() error: we previously assumed 'head_pipe' could be null (see line 1010)\n\ud83d\udccf Published: 2024-10-21T18:01:45.769Z\n\ud83d\udccf Modified: 2025-02-21T13:45:10.419Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/16ce8fd94da8599bb6f0496895d392a69aead1c0\n2. https://git.kernel.org/stable/c/390d757621f5f35d11a63ed7d9d3262ead240064\n3. https://git.kernel.org/stable/c/8a1b1655a490a492a5a6987254c935ecce4eb9de\n4. https://git.kernel.org/stable/c/f22f4754aaa47d8c59f166ba3042182859e5dff7", "creation_timestamp": "2025-02-21T14:18:33.000000Z"}
