There's a stub for pm_runtime_active for !PM which does the right thing here, no need for ifdefs.
- /*configure PM */
- pm_runtime_set_autosuspend_delay(bus->dev, SKL_SUSPEND_DELAY);
- pm_runtime_use_autosuspend(bus->dev);
- pm_runtime_put_noidle(bus->dev);
- pm_runtime_allow(bus->dev);
- pci_set_drvdata(skl->pci, ebus);
Shouldn't you be setting the driver data before you register the device and enable PM? Otherwise the PM callbacks might run without it being set.
+out_free:
- skl->init_failed = 1;
- skl_free(ebus);
- pci_set_drvdata(skl->pci, NULL);
No need to set the driver data to NULL, the driver core will do it.
