raspberry pi kernel 4.14 driver compile warning

Using the source from https://github.com/genodeftest/Netgear-A6210/tree/port-to-4.14 to compile the driver for raspberry pi kernel 4.14 I'm getting a warning:-

Can anyone help fix it.

A similar warning re:- memcpy has been fixed so hopefully this can be to.

Reporting here as there doesn't seem to be the option of reporting issues at github.com/genodeftest.
