[ Upstream commit 3b577de206d52dbde9428664b6d823d35a803d75 ]
It's important to undo pm_runtime_use_autosuspend() with pm_runtime_dont_use_autosuspend() at driver exit time unless driver initially enabled pm_runtime with devm_pm_runtime_enable() (which handles it for you).
Hence, call pm_runtime_dont_use_autosuspend() at driver exit time to fix it.
