Acked-by: Bjorn Helgaas <bhelg...@google.com> # drivers/pci/ - Previous PM history uses "PM: " in the subject lines (not "pm: "). - I don't know whether it's feasible, but it would be nice if the intel_pm_runtime_pm.c rework could be done in one shot instead of being split between patches 1/3 and 2/3. Maybe it could be a preliminary patch that uses the existing if_active/if_in_use interfaces, followed by the trivial if_active updates in this patch. I think that would make the history easier to read than having the transitory pm_runtime_get_conditional() in the middle. - Similarly, it would be nice if pm_runtime_get_conditional() never had to be published in pm_runtime.h, instead of being temporarily added there by this patch and then immediately made private by 2/3. Maybe that's not practical, I dunno. Bjorn
