[ Upstream commit 22a07038c0eaf4d1315a493ce66dcd255accba19 ]
The Parfait (version 2.1.0) static code analysis tool found the following NULL pointer derefernce problem.
- drivers/gpu/drm/drm_dp_mst_topology.c
The call to drm_dp_calculate_rad() in function drm_dp_port_setup_pdt() could result in a NULL pointer being returned to port->mstb due to a failure to allocate memory for port->mstb.
