CVS commit: src/sys/dev

[David Young <dyoung%netbsd.org@localhost>]

Module Name:    src
Committed By:   dyoung
Date:           Tue Apr  7 22:30:09 UTC 2009

Modified Files:
        src/sys/dev/ic: attimer.c attimervar.h
        src/sys/dev/isa: pcppi.c

Log Message:
Make pcppi(4) detach the "speaker" from attimer(4), so that the
corresponding attimer(4) resource is not perpetually busy: now it
is possible to detach and to reattach pcppi(4).  Make attimer(4)'s
device-detachment hook return EBUSY if pcppi(4) is still attached, so
that pcppi(4) cannot end up with a dangling pointer to attimer(4).
