uartEnd: Unlock mutex before detaching rx and tx (#554)
* uartEnd: Unlock mutex before detaching rx and tx This should solve the device freezing issue when Serial.end() is called * Unlock UART MUTEX only for detaching Rx and Tx * Thanks to @me-no-dev for pointing it out that uart->dev->conf0.val can be inside mutex lock
