[patch] scsi/qla2xxx: checking for null cleanups

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



These are two cleanups to make the static checkers happy.  The "vha" is 
used as the list cursor and can never be null so I removed the check.  I 
also modified qla2x00_request_firmware() to avoid a theoretical null
dereference.  This is unlikely to happen I think, but it makes auditing
easier.
