'default N' should be 'default n', though they happen to have the same
effect here, due to undefined symbols (N in this case) evaluating to n
in a tristate sense.

Remove the default instead of changing it. bool and tristate symbols
implicitly default to n.

Discovered with the
https://github.com/ulfalizer/Kconfiglib/blob/master/examples/list_undefined.py
script.

Since only this patch was posted to linux-pci, I assume it will be merged
via some other tree.

Not a great excuse, but I was thinking syntactically -- 'bool' and
'tristate' symbols... :)

I didn't have a particular tree in mind for this patchset. I imagined
people would pick up patches into the trees where they make the most
sense, and only created the patchset to keep track of the patches more
easily. Might have created some confusion in retrospect.

I just did a --cc-cmd="scripts/get_maintainer.pl -i" for the
individual patches by the way.

Cheers,
Ulf

OK, then either Lorenzo or I will pick it up.

It's in drivers/pci/host/, so ideally Lorenzo will take it since he
looks after everything else in there.

I have remove this link - it can become stale so I do not think it is
worth adding it to the log.

I have also reworded the $SUBJECT.

Applied to pci/host/misc for v4.17, let me know if that's fine for you.

Thanks,
Lorenzo
