- Add detach support to the driver so that you can kldunload the module. Note that currently rc_detach() fails to detach a unit if any of its child devices are open, thus a kldunload will fail if any of the tty devices are currently open. - sys/i386/isa/ic/cd180.h was moved to sys/dev/ic/cd180.h as part of this change.
