serial: trim locking on the helpers
The port mutex protects port->tty, but these paths never need to walk from port->tty. They do need the low level lock as the API expects that but they already also take it. Thus we can drop the extra mutex lock calls here. Signed-off-by: Alan Cox <alan@linux.intel.com> Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
