H A D | sdhci-pxav3.c | 0dcaa249 Thu Jun 27 10:46:29 CDT 2013 Daniel Drake <dsd@laptop.org> sdhci-pxav3: Fix runtime PM initialization
Commit bb691ae464b77d30e74c66480e98d74e88d6b194 breaks boot on OLPC XO-4, it hangs somewhere inside sdhci_add_host.
When pm_runtime_set_autosuspend_delay() was being called, the device's usage counter was 0, causing the PM layer to runtime-suspend the device. We then went on to call sdhci_add_host() on a suspended device, which hung.
Fix this by making the driver consistent with the omap_hsmmc driver, both in terms of runtime PM initialization and error handling. Now the device is not runtime-suspended until we exit the probe routine.
