On this platform (ACPI-based) there are no other possibilities to get
something meaningful that can be returned (deferred probe). The rest
of the error codes will actually regress since the user won't have a
pin control driver at all, instead of having it IRQ-less (which is
doubtfully useful, though). Have you considered that scenario?
