Yes, I have already converted to using __be16 where needed, it will be
in the next version of the patch I send.

I can forward declare these (copying from the header I used in v1 of
the patch), but I'm not sure I understand the rationale behind these
warnings...

Especially this. I think I will make this static instead, since it
won't ever be exported to any other module.

The lkp bot complained about MODULE_DEVICE_TABLE and MODULE_AUTHOR,
which, again, I don't see what is wrong with it.

I thought this was the correct way of strncpy... Time to RTFM then, I guess :)

Sure!

I will now send an updated patch, with  few additions too.
