Subject: usb: typec: tcpm: Move mod_delayed_work(&port->vdm_state_machine)
 call into tcpm_queue_vdm()
Git-commit: 5f2b8d87bca528616e04344d1fc4032dc5ec0f3d
Patch-mainline: v5.9-rc1
References: jsc#SLE-13918

All callers of tcpm_queue_vdm() immediately follow the tcpm_queue_vdm()
vdm call with a:

	mod_delayed_work(port->wq, &port->vdm_state_machine, 0);

Call, fold this into tcpm_queue_vdm() itself.
