Hi, just use the MMC_CAP2_SDIO_IRQ_NOTHREAD? if (!err && host->sdio_irq && !(host->quirks & MMC_CAP2_SDIO_IRQ_NOTHREAD)) wake_up_process(host->sdio_irq_thread); I didn't test this..but i believe that it will be fixed.

In some cases, this will make "host->sdio_irq_thread" a NULL pointer in "mmc_sdio_resume" functon of core/sdio.c file and lead to resume failure. Could you please give me some advice how to fix this bug? > > > > Thanks, > Zhonghui > > > > > > -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
