But when it is failed to build connection with GPU for one case that integrated graphic gpu is disabled, snd_hdac_ext_bus_device_exit will be invoked to clean up a HD-audio extended codec base device. At this time the child_count of parent is not decreased, which makes parent device can't get suspended. This patch calls pm_runtime_set_suspended to decrease child_count in parent device in snd_hdac_device_exit to match with snd_hdac_device_init. pm_runtime_set_suspended can make sure that it will not decrease child_count if the device is already suspended.
