IIUC, devm_led_classdev_register() uses the first argument both
to manage unregistering on unbind, but also as parent of the LED device.

While the former is desired, the latter likely is not.
I assume the LEDs now appear as children of the PCI device in sysfs,
not as children of the netdev.  Probably not what you want.

The second patch I posted should handle that correctly.

Thanks,

Lukas
