* stm32: fix USART ORE status flag handlingAlex Voinea2022-10-311-1/+4
| | | | | | | | | | | If an USART RX overrun happened on a stm32g0/f0/h7, the ORE flag would get set by hardware. This flag would also trigger an interrupt. The problem was that this flag was never cleared on these 3 mcu families since the ORE flag clear sequence is different to all of the older chips. Since the ORE flag is not used in any meaningful way anyway, it was disabled during the init sequence. Signed-off-by: Alex Voinea <voinea.dragos.alexandru@gmail.com>
