This patch is wrong, because it causes build errors:

drivers/amba/bus.c:126:18: error: 'pm_generic_suspend_late' undeclared here (not in a function)
drivers/amba/bus.c:127:18: error: 'pm_generic_resume_early' undeclared here (not in a function)
drivers/amba/bus.c:128:17: error: 'pm_generic_freeze_late' undeclared here (not in a function)
drivers/amba/bus.c:129:16: error: 'pm_generic_thaw_early' undeclared here (not in a function)
drivers/amba/bus.c:130:19: error: 'pm_generic_poweroff_late' undeclared here (not in a function)
drivers/amba/bus.c:131:19: error: 'pm_generic_restore_early' undeclared here (not in a function)

The failing configuration is:

# CONFIG_SUSPEND is not set
CONFIG_PM_RUNTIME=y
CONFIG_PM=y
