stable inclusion from linux-4.19.198 commit c7a13cbc42793ae74a2dff3fd7f543425830258f
--------------------------------
[ Upstream commit a51b2fb94b04ab71e53a71b9fad03fa826941254 ]
Return value of "pm_runtime_get_sync" API was neither captured nor checked. Fixed it by capturing the return value and then checking for any warning.
