I think I have seen this fail occasionally when something's wrong in the
IRQ code, or when we are not properly configuring the IRQ in device tree
for example.
So I'd prefer if this error message stayed here. I agree that it's not a
terribly useful error message, so perhaps adding the error code to it
would make it more helpful?
