If pm_runtime_resume_and_get() failed with -EACCES, the driver continued execution and finally called pm_runtime_put_autosuspend(). Since pm_runtime_resume_and_get() drops the usage counter on every error, this lead to double decrement of that counter visible in certain debugfs actions on unattached devices (still in reset state):
