Git-commit: bb46737ec09e9a072424bf46def2977c5b6b925d
References: bsc#1157169

drivers/scsi/qla2xxx/qla_dbg.c:2542:7: warning: The scope of the variable 'pbuf'
can be reduced. [variableScope]
drivers/scsi/qla2xxx/qla_init.c:3615:6: warning: Variable 'rc' is assigned a
value that is never used. [unreadVariable]
drivers/scsi/qla2xxx/qla_isr.c:81:11-29: WARNING: dma_alloc_coherent use in
rsp_els already zeroes out memory, so memset is not needed
drivers/scsi/qla2xxx/qla_mbx.c:4889:15-33: WARNING: dma_alloc_coherent use in
