    Hi Himanshu,
    
    This reverts commit 0bfe7d3cae58 ("scsi: qla2xxx: Simplify conditional
    check") and reintroduces the clang warning that it fixed. Was there a
    particular reason for this?
    
    Thanks,
    Nathan

This looks like oversight during code merging. Would you please resend the 
patch.
