Hi,
Poul's recent cdevsw changes to -current have broken the
bt848/bt878 bktr driver.

Not quite a NO-OP, but the slip up was a subtle one and easy
to get wrong.
The new cdevsw code uses a new function call
which is added to the bktr_probe() function.
cdevsw_add(&bktr_cdevsw);
Unfortunatly it was added to the BSDI bktr_probe() code and
not the FreeBSD bktr_probe() code.
#ifdef __bsdi__
.. blah blah blah
.. bktr_probe() <- cdev change went here
.. blah blah blah
#endif
#ifdef __FreeBSD__
.. blah blah blah
.. bktr_probe() <- it should be here
.. blah blah blah
#endif
THE FIX...
Move the following 3 lines
static int once;
if (!once++)
cdevsw_add(&bktr_cdevsw);
from the _BSDI_ bktr_probe
to the _FreeBSD_ bktr_probe
and it should all work.
I'll try and do a commit this evening, when I can test it.
It is temping to rip out the BSDI code.
Althouth the NetBSD/OpenBSD people want me to add their patches to the
source.
Bye
Roger
