When 7c7f9bc986e6 ("serial: Deassert Transmit Enable on probe in driver-specific way") got backported to 5.15.y, there known as b079d3775237, this hunk was accidentally left out. So if the "goto failed_get_rs485;" is hit, the cleanup will do uart_remove_one_port() despite uart_add_one_port() not having been called.
Add the missing hunk.
