This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable. Benefits of this change: * unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n and CONFIG_PM_RUNTIME=y configurations * easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in the future * more consistent code (there are host drivers which are using the correct CONFIG_PM_SLEEP checks already) The patch leaves the core libata code and ->port_[suspend,resume] support in sata_[inic162x,nv,sil24].c alone for now.
