Currently, tmio_mmc_irq() handler is registered before the host is fully initialized by tmio_mmc_host_probe(). I did not previously notice this problem. The boot ROM of a new Socionext SoC unmasks interrupts (CTL_IRQ_MASK) somehow. The handler is invoked before tmio_mmc_host_probe(), then emits noisy call trace. Move devm_request_irq() below tmio_mmc_host_probe().
