Even if the identifier string of tty3270.c becomes "3270/tty" it seems
that something goes wrong as in show_cons_active() of drivers/tty/tty_io.c
the name_base of the struct tty_driver is not honored.
Also on s390 the device for "3270/tty" its self is not plugged:
systemctl list-units | grep virtual-tty | sed 's/^/ /'
sys-devices-virtual-tty-hvc0.device loaded active plugged
/sys/devices/virtual/tty/hvc0

sys-devices-virtual-tty-ttysclp0.device loaded active plugged
/sys/devices/virtual/tty/ttysclp0
as the existing directory
/sys/devices/virtual/tty/3270!tty1
is not listed at least with 208. Nevertheless the nodes are there
ll /dev/3270/tty1
crw--w---- 1 root tty 227, 1 Feb 4 15:51 /dev/3270/tty1
but a `dev-3270-tty1.device' seems not to be usable.
