sys/dev/pccbb pccbb.c
Log:
It turns out that it is easier to not NULL out pccard and cardbus
device pointers. They don't change as the children device drivers
come and go. Rather, check to see if the device is attached where we
would have checked ! NULL. This solves many asymmetries in the code
that likely could lead to crashes when loading/unloading cbb without
one or more of the expected children's driver not present.
