Problema de pérdida de memoria en ax25_addr_ax25dev(): el recuento de referencias del objeto \"ax25_dev\" se puede aumentar varias veces en ax25_addr_ax25dev(). Esto provocará una pérdida de memoria. Problemas de pérdida de memoria en ax25_dev_device_down(): el recuento de referencias de ax25_dev se establece en 1 en ax25_dev_device_up() y luego aumenta el recuento de referencias cuando se agrega ax25_dev a ax25_dev_list.

El ax25_dev_device_down() reduce el recuento de referencias una o dos veces dependiendo de si vamos a unlock_put o no, lo que provocará una pérdida de memoria. En cuanto al problema de ax25_addr_ax25dev(), es imposible que un puntero esté en una lista dos veces. Entonces agregue una interrupción en ax25_addr_ax25dev().
