What happens when building the driver on a platform that includes neither OF
nor ACPI support ?

How have you checked that you haven't missed any entry in the Kconfig files ?

vfwn is confusing to me, I think the variable name should show that it refers
to an endpoint.

Is there no way to keep the node name in the error message ?

As explained in the review of another patch from the same series, I wouldn't
rename the variable.

This change doesn't seem to be needed.

This makes me believe that we're missing a fwnode_full_name() function.

This probably belongs to another patch (at least the alphabetical sorting
does).
