commit 2eb3da037c2c20fa30bc502bc092479b2a1aaae2 upstream.
As PD2.0 spec ("8.3.3.2.3 PE_SRC_Send_Capabilities state"), after the Source receives the GoodCRC Message from the Sink in response to the Source_Capabilities message, it should start the SenderResponseTimer, after the timer times out, the state machine transitions to the HARD_RESET state.
