The sdhci_omap_runtime_suspend() calls sdhci_runtime_suspend_host() but does not handle the return value. A proper implementation can be found in sdhci_am654_runtime_suspend().

Add error handling for sdhci_runtime_suspend_host(). Return the error code if the suspend fails.

I think it's better to remove the return value instead:
