CVS commit: src/sys/dev/ata

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

Module Name:    src
Committed By:   dyoung
Date:           Fri Apr  3 21:31:08 UTC 2009

Modified Files:
        src/sys/dev/ata: ata.c

Log Message:
Stop dereferencing a dangling device_t pointer and crashing: skip the
drives flagged DRIVE_ATAPI in atabus_activate(,DVACT_DEACTIVATE) just as
we skip them in atabus_detach() and in atabus_childdetched().

Make atabus_detach() parallel attachment more closely by calling
config_detach() on the child chp->ata_drives[i] instead of on
chp->ch_drive[i].drv_softc.  Assert that ata_drives[i] and
ch_drive[i].drv_softc are equal, and set them both to NULL in
atabus_childdetached().
