> Subsequently, f32a21376573 ("ethtool: runtime-resume netdev parent before
> ethtool ioctl ops") added pm_runtime_get_sync() in the dev_ethtool() path,
> so the device is resumed before any ethtool_ops callback even if the driver
> didn't supply a .begin() callback.
>
> Remove the .begin() and .complete() callbacks, which are now redundant
> because dev_ethtool() already resumes the device.
