5.4-stable review patch. If anyone has any objections, please let me know.

commit 2a20869f7d798aa2b69e45b863eaf1b1ecf98278 upstream.
It is not valid to call pm_runtime_set_suspended() for devices with runtime PM enabled because it returns -EAGAIN if it is enabled already and working. So, call pm_runtime_disable() before to fix it.
