* reset: renesas: Fix Runtime PM usageHeiner Kallweit2021-12-151-1/+6
| | | | | | | | | | | | | If pm_runtime_resume_and_get() fails then it returns w/o the RPM usage counter being incremented. In this case call pm_runtime_put() in remove() will result in a usage counter imbalance. Therefore check the return code of pm_runtime_resume_and_get() and bail out in case of error.
