Hi Jisheng,
Thanks for your patch but it needs to be updated since it breaks this
driver.
- struct sdhci_at91_priv *priv = pltfm_host->priv;
+ struct sdhci_at91_priv *priv = sdhci_pltfm_priv(pltfm_host);
is missing in sdhci_at91_runtime_suspend and sdhci_at91_runtime_resume
causing a NULL pointer dereference.

Can be on the same line.
