Also this check seems like it will be hard to keep in sync as things change. Assuming this error check is actually necessary, would it be perhaps better to check i is smaller than ARRAY_SIZE(cs35l45_irqs) and check that the attached function is cs35l45_spk_safe_err. That should be more robust against future changes to the IRQs. Thanks, Charles
