pm_runtime_get_sync will increment the PM reference count even failed. Forgetting to putting operation will result in a reference leak here.
Replace it with pm_runtime_resume_and_get to keep usage counter balanced.
BTW, pm_runtime_resume_and_get is introduced in v5.10-rc5 as dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to dealwith usage counter")
