  "message": "usb: typec: tcpm: Wait in SNK_DEBOUNCED until disconnect\n\nStub from the spec:\n\"4.5.2.2.4.2 Exiting from AttachWait.SNK State\nA Sink shall transition to Unattached.SNK when the state of both\nthe CC1 and CC2 pins is SNK.Open for at least tPDDebounce.\nA DRP shall transition to Unattached.SRC when the state of both\nthe CC1 and CC2 pins is SNK.Open for at least tPDDebounce.\"\n\nThis change makes TCPM to wait in SNK_DEBOUNCED state until\nCC1 and CC2 pins is SNK.Open for at least tPDDebounce. Previously,\nTCPM resets the port if vbus is not present in PD_T_PS_SOURCE_ON.\nThis causes TCPM to loop continuously when connected to a\nfaulty power source that does not present vbus.
