ERROR_NONE?

Using 0 here might be better than using
static_cast<int>(HostPairingController::ErrorCode::ERROR_NONE) here as
|enrollment_error_code_| may be a value that is not in the enum class
HostPairingController::ErrorCode.

 
   // Current stage of pairing process.
   Stage current_stage_ = pairing_chromeos::HostPairingController::STAGE_NONE;
