This ave driver uses devm_allocate_etherdev() to allocate "ndev".
It will be released automatically when removing the driver.
Therefore, it is not necessary to release it explicitly.
Please refer to the commit e87fb82ddc3b
("net: ethernet: ave: Replace alloc_etherdev() with devm_alloc_etherdev()").
Thank you,
