Driver remove() must call pm_runtime_dont_use_autosuspend().
Drivers that call pm_runtime_use_autosuspend() must disable it in driver remove(). Unfortunately until recently this was only mentioned in 1 line in a 900+ line document so most people hadn't noticed this. It has only recently been added to the kerneldoc of pm_runtime_use_autosuspend().
