From what I can tell, it seems like ->cmd_host2risc() is only ever
called from v6 code, which always passes NULL? It seems like it should
be possible to just drop .cmd_host2risc on the v5 side, then update
.cmd_host2risc to only take two parameters? If so, I can send a follow
up as a clean up, so that this can go back relatively conflict free.

It seems so yes. For this specific patch, I would probably rename "args" to
"__unused" to make the reading faster. But does not matter so much if you
later
remove it.

Yes, after this change is picked up in a maintainer's tree, I do plan to
send a patch to remove the "args" parameter altogether. If you really
care, I can certainly rename the parameter in this change to "__unused"
as suggested but if you don't, I will just leave it as is to make
backporting this a little easier.

Thanks a lot for taking a look!

While applying your patch, I realized the Hans merged another version of this
fix, but made by Arnd. It covers the remaining too, so I will mark yours as
superseded now.
