Resulta que hay m\u00e1s que solo la ruta mencionada anteriormente que hace que esto suceda (por ejemplo, el caso cuando hay datos de speedbin en el cat\u00e1logo, pero opp-supported-hw falta en DT). Asignar msm_gpu->pdev antes parece ser la soluci\u00f3n menos dolorosa para esto, as\u00ed que hazlo.
