cdevsw_add is called in devsw_module_handler and in bktr_probe. Patch
attached. It looks like the init in bktr_probe became superfluous in
revision 1.90 of brooktree848.c:
revision 1.90
date: 1999/08/23 20:59:12; author: phk; state: Exp; lines: +7 -20
Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.
Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)
Add the correct hook for devfs to kern_conf.c
The net result of this excercise is that a lot less files depends on
DEVFS,
and devtoname() gets more sensible output in many cases.
A few drivers had minor additional cleanups performed relating to cdevsw
registration.
A few drivers don't register a cdevsw{} anymore, but only use
make_dev().
