From 8270ee2abb78c73b73e04f2909b0de15540c9017 Mon Sep 17 00:00:00 2001 From: Santosh Nayak Date: Sun, 26 Feb 2012 20:14:46 +0530 Subject: [PATCH] [SCSI] pm8001: fix endian issue with code optimization. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 1. Fix endian issue. 2. Fix the following warning : " drivers/scsi/pm8001/pm8001_hwi.c:2932:32: warning: comparison between ‘enum sas_device_type’ and ‘enum sas_dev_type’". 3. Few code optimization.
