[PATCH 1/2] mmc: sdhci-esdhc-imx: Manage sdhci_runtime_suspend_host error code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We need to return in case of error even if the actual implementation
of sdhci_runtime_suspend_host always return 0. We don't want to
power down the clocks and the assuption is that the sdhci_runtime_suspend_host
always let the system consistent in case of failure
