One bug of SDHCI driver

[Fu, Zhonghui]

Hi, all

The statement "mmc->caps2 |= MMC_CAP2_SDIO_IRQ_NOTHREAD;" is added in "sdhci_add_host" function in host/sdhci.c file. 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
