Se corrige un error en el kernel detectado al probar el controlador de endpoint stm32_pcie con el manejo de la deaserción PERST#: Durante la inicialización de EP, pci_epf_test_alloc_space() asigna todos los BAR, que se liberan aún más si epc_set_bar() falla (por ejemplo, debido a que no hay una ventana de entrada libre). Sin embargo, cuando pci_epc_set_bar() falla, la ruta de error: pci_epc_set_bar() -> pci_epf_free_space() no borra la asignación previa a epf_test->reg[bar]. Luego, si el host se reinicia, la desasignación PERST# reinicia la secuencia de asignación de BAR con el mismo fallo de asignación (sin ventana de entrada libre), lo que crea una situación de doble liberación, ya que epf_test->reg[bar] se desasignó y sigue siendo distinto de NULL. Por lo tanto, asegúrese de que las invocaciones de pci_epf_alloc_space() y pci_epf_free_space() sean simétricas y, por lo tanto, establezca epf_test->reg[bar] en NULL cuando se libere memoria.
