I noticed that mmc: litex_mmc handles the return value from platform_get_irq_optional() correctly, distinguishing the case where an optional IRQ is not available from other errors. This series follows the same approach in the affected drivers. Changes in v2: - Use parse_fail for proper cleanup on IRQ lookup errors. - Initialize cd_irq to -ENXIO.
