commit c0dd36bcb67fdabc23a0f4fa79e543bffbf980c2
bugzilla: 175263 https://gitee.com/openeuler/kernel/issues/I4DT6F

--------------------------------

[ Upstream commit 69777e6c ]

pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here.
Fix it by replacing it with pm_runtime_resume_and_get to keep usage
counter balanced.
