CVS commit: src/sys/dev/pci

[Christoph Egger <cegger%netbsd.org@localhost>]

Module Name:    src
Committed By:   cegger
Date:           Sun Mar  1 13:34:10 UTC 2009

Modified Files:
        src/sys/dev/pci: if_nfe.c

Log Message:
when nfe_attach() fails, free all resources including
interrupt map, interrupt handler and dma maps.
Also prevent call to bus_dmamap_destroy() when bus_dmamap_create() failed.
The nfe_free_* routines assume, the map pointers are NULL but they
are actually undefined. Make the assumption true by making them NULL
in the error path of bus_dmamap_create().

All together, this fixes crashes when nfe_attach() fails.
