From: Jos Wang <joswang@xxxxxxxxxx>
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.
Fixes: f0690a25a140 ("staging: typec: USB Type-C Port Manager (tcpm)")
