If pm_runtime_set_autosuspend_delay() is not suitable for the task then
maybe we need a better API. I will admit I'm at a loss when it comes to
the many pm_runtime_* calls, I'm not going to claim I fully understand
what each of them is doing exactly. But don't we want to simply call
pm_runtime_dont_use_autosuspend() here?

If not and there's no suitable API for the task at the moment, then
better do not apply this patch, and instead ask the PM subsystem
maintainers if they would be willing to implement what we need.

To follow-up on this: This patch has been applied already. Therefore,
if decision is to not go with it, it would need to be reverted.

Technically it's not in Linus' tree yet ;-)

I'm still interested to know if pm_runtime_dont_use_autosuspend() is
the right call to use in this situation.
