Only CS7 and CS8 seem supported but CSIZE is not sanitized to CS8 in the default: block. Set CSIZE correctly so that userspace knows the effective value. Incorrect CSIZE also results in miscalculation of the frame bits in tty_get_char_size() or in its predecessor where the roughly the same code is directly within uart_update_timeout().
