Modified files:
sys/kern tty_cons.c
Log:
Don't follow null pointers if we somehow have a null devswitch entry
despite having a non-null cn_tab entry. This case now works the same
as if there is no physical console, except i/o at the kernel printf
level may still work. This frees drivers of physical console drivers
from the responsibility of attaching the device no matter what.
