From 56b5871223f66d4a34e6e1069f241077e9f0a154 Mon Sep 17 00:00:00 2001 From: Mark Haverkamp Date: Wed, 27 Apr 2005 06:05:51 -0700 Subject: [SCSI] aacraid: remove sparse warnings This patch addresses the sparse -Wbitwise warnings that Christoph wanted me to eliminate. This mostly consisted of making data structure elements of hardware associated structures the __le* equivalent. Although there were a couple places where there was mixing of cpu and le variable math. These changes have been tested on both an x86 and ppc machine running bonnie++. The usage of the LE32_ALL_ONES macro has been eliminated.
