scsi: qla2xxx: Cleanup FC-NVMe code
This patch does not change any functionality. Following cleanups have been done as requested by reviewer - Changed waitQ --> waitq - Collapsed multiple debug statements into single - Remove extra parentheses in if-else as per operator precedence - Remove unnecessary casting Cc: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Himanshu Madhani <himanshu.madhani@cavium.com> Reviewed-by: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Martin K.
