The pm_runtime_get_sync() internally increments the dev->power.usage_count without decrementing it, even on errors. replace it by the new pm_runtime_resume_and_get(), introduced by: commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter") in order to properly decrement the usage counter and avoid memory leaks.
