Bug report: Incorrect validation in com port initalization of nucleo (G4) BSP

[lamare]

When using the register callbacks feature ( USE_HAL_UART_REGISTER_CALLBACKS = 1) , the BSP does not register the default callback, causing the serial port not to work. 

Fix:

Hi @lamare 

Do you configured the uart interrupt line and Nvic ?
