Using dm after free_netdev()\ncan cause UAF bug. Fix it by moving free_netdev() at the end of the\nfunction.\n\nThis is similar to the issue fixed in commit\nad297cd2db89 (\"net: qcom/emac: fix UAF in emac_remove\").\n\nThis bug is detected by our static analysis tool."

El uso de dm despu\u00e9s de free_netdev() puede provocar un error de UAF. Solucione el problema moviendo free_netdev() al final de la funci\u00f3n.
