           Summary: [CHECKER] Return value of idr_find not checked for NULL
           Product: OpenIB
           Version: gen2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal

        ReportedBy: bos at pathscale.com


This is unlikely to be a real bug, but idr_find *can* return NULL.  In our case,
whoever added something to the idr probably bombed out if the add failed, so we
won't get called.  Maybe :-)
