From fec3c1b4575431e2020c5c6502d18b281925ca45 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 29 Jun 2013 00:21:04 +0300 Subject: [PATCH] [SCSI] megaraid_sas: fix a bug for 64 bit arches On 64 bit then -1UL and -1U are not equal, so these conditions don't work as intended and it breaks error handling.
