If anyone has any objections, please let me know. ------------------ From: Oleksij Rempel [ Upstream commit e863ff806f72098bccaf8fa89c80d9ad6187c3b0 ] Validate Wake-on-LAN (WoL) options in `lan78xx_set_wol` before calling `usb_autopm_get_interface`. This prevents USB autopm refcounting issues and ensures the adapter can properly enter autosuspend when invalid WoL options are provided.
