From: Hugo Villeneuve <[email protected]> The minimum baud rate supported by this driver is 0, so even for the B0 case, uart_get_baud_rate() will return 9600, not zero. This check is no longer necessary since commit 16ae2a877bf4 ("serial: Fix crash if the minimum rate of the device is > 9600 baud") so remove it.
