From c345c6ca13825d1a15de5399226802433dd30f8c Mon Sep 17 00:00:00 2001 From: Himanshu Madhani Date: Fri, 30 Jun 2017 19:32:53 -0700 Subject: qla2xxx: Fix NVMe entry_type for iocb packet on BE system This patch fixes incorrect assignment for entry_type field for Continuation Type iocb packet on BE system. This was caught by -Woverflow warning on BE system compilation. For Continuation Type iocb driver needs to write complete 32 bit value to initialize other field members in structure to 0. Following warning is seen on BE system compile: drivers/scsi/qla2xxx/qla_nvme.c: In function 'qla2x00_start_nvme_mq': include/uapi/linux/byteorder/big_endian.h:32:26: warning: large integer implicitly truncated to unsigned type [-Woverflow] #define __cpu_to_le32(x) ((__force __le32)__swab32((x))) [mkp: fixed typo] Signed-off-by: Himanshu Madhani Signed-off-by: Martin K.
