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.
Best Regards, Jaehoon Chung

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 > > > > > >
