From: Mukesh Sisodiya <mukesh.sisodiya@xxxxxxxxx> During debugfs command handling transport function is used directly, this bypasses the locking used by runtime operation function and leads to a kernel warning when two commands are sent in parallel. Fix it by using runtime operations function when sending debugfs command.
