[PATCH v4 8/8] drm/nouveau: Call pm_runtime_get_noresume() from hpd handlers
...play before the runtime_suspend worker disables
hotplug interrupts in nouveau_display_fini()
3. hotplug is handled, display is lit up
4. runtime_suspend worker waits for hotplug handler to finish
5. GPU is runtime suspended and the newly plugged in display goes black
The call to pm_runtime_mark_last_busy() has no effect in this situation
because rpm_suspend() doesn't look at the last_busy variable after the
call to rpm_callback(). What's necessary here is that runtime_suspend is
aborted and -EBUSY returned.
Thanks,
Lukas
