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. Instead of only checking for -EPROBE_DEFER, propagate all error codes returned by platform_get_irq_optional() other than -ENXIO, so that failures are properly reported to the caller.
