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 optional IRQ is available, while other errors should be propagated. Propagate all error codes returned by platform_get_irq_optional() other than -ENXIO. Another call to platform_get_irq_optional() in the same function already handles the return value this way. Apply the same error handling to this call site for consistency.
