[SCSI] aacraid: incorrect dma mapping mask during blinkled recover or user initiated reset
Incorrect dma mask was used for blinkled (firmware assert) recovery or user initiated reset during initialization portion. Ensure that all callers of aac_fib_map_free null out the fib allocation references to prevent multiple free. Although serious sounding, no reports of these problems have surfaced...
