From: bui duc phuc <[email protected]> platform_get_irq_optional() returns a positive IRQ number on success or a negative error code on failure. For an optional IRQ, -ENXIO indicates that no IRQ is available, while other errors should be propagated. Propagate errors such as -EPROBE_DEFER and -EINVAL instead of continuing probe without the IRQ.
