From 6f359f99b8c2ff3b09329611da00fe39a7c10e7e Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 20 Mar 2017 09:49:27 +0100 Subject: [PATCH] qedf: fix wrong le16 conversion gcc points out that we are converting a 16-bit integer into a 32-bit little-endian type and assigning that to 16-bit little-endian will end up with a zero: drivers/scsi/qedf/drv_fcoe_fw_funcs.c: In function 'init_initiator_rw_fcoe_task': include/uapi/linux/byteorder/big_endian.h:32:26: error: large integer implicitly truncated to unsigned type [-Werror=overflow] t_st_ctx->read_write.rx_id = cpu_to_le32(FCOE_RX_ID); The correct solution appears to be to just use a 16-bit byte swap instead.
