Neither platform based nor dt based device needs to pass the parent to sdhci_alloc_host. There is no difference between platform and dt on this point. The patch makes the change to pass device itself than its parent to sdhci_alloc_host for dt case too. Otherwise the probe function of sdhci based drivers which is shared between platform and dt will fail on dt case.
