When the pm_runtime_force_suspend|resume() helpers were invented, we still had CONFIG_PM_RUNTIME and CONFIG_PM_SLEEP as separate Kconfig options. To make sure these helpers worked for all combinations and without introducing too much of complexity, the device was always resumed in pm_runtime_force_resume(). More precisely, when CONFIG_PM_SLEEP was set and CONFIG_PM_RUNTIME was unset, we needed to resume the device as the subsystem/driver couldn't rely on using runtime PM to do it. As the CONFIG_PM_RUNTIME option was merged into CONFIG_PM a while ago, it removed this combination, of using CONFIG_PM_SLEEP without the earlier CONFIG_PM_RUNTIME. For this reason we can now rely on the subsystem/driver to use runtime PM to resume the device, instead of forcing that to be done in all cases. In other words, let's defer the runtime resume to a later point when it's actually needed.
