Hi tglx, Please refer to drivers/mmc/host/sdhci.c. sdhci uses sdhci_irq and sdhci_thread_irq as the followings. 3366 sdhci_init(host, 0); 3367 3368 ret = request_threaded_irq(host->irq, sdhci_irq, sdhci_thread_irq, 3369 IRQF_SHARED, mmc_hostname(mmc), host); When I tested SDIO card, sdhci_irq() was not called after 1st SDIO interrupt. After I applied my patch, this worked good.
