From 3e6f7de43f4960fba8322b16531b0d6624a9322d Mon Sep 17 00:00:00 2001 From: Tyrel Datwyler Date: Wed, 20 Mar 2019 14:56:53 -0500 Subject: [PATCH] scsi: ibmvfc: Byte swap status and error codes when logging Status and error codes are returned in big endian from the VIOS. The values are translated into a human readable format when logged, but the values are also logged. This patch byte swaps those values so that they are consistent between BE and LE platforms.
