STM32 serial RX/TX active patch

jeromecoutant · jeromecoutant · commit 3721ac44d2cc · 2018-06-28T18:05:52.000+02:00
In serial_tx_active and serial_rx_active functions,
we check the internal state value with

HAL_UART_STATE_BUSY_TX = 0x21U,
HAL_UART_STATE_BUSY_RX = 0x22U,

It seems that value can also be :
HAL_UART_STATE_BUSY_TX_RX = 0x23U,
