serialEventRun() has typo calls serialEvent() for all ports

[RickKimball]

https://github.com/stm32duino/Arduino_Core_STM32/blob/master/variants/NUCLEO_F091RC/variant.cpp#L111-L112 is an example however it appears that is a problem in multiple variant.cpp files.

void serialEventRun(void)
{
  if (Serial.available()) serialEvent();
  if (Serial1.available()) serialEvent();
  if (Serial2.available()) serialEvent();
}

This should probably be

void serialEventRun(void)
{
  if (Serial.available()) serialEvent();
  if (Serial1.available()) serialEvent1();
  if (Serial2.available()) serialEvent2();
}

Just put this;

in loop or whatever your function is,

if (Serial.available>())
serialEvent();
