From 902a45af5c9fad283a530c3bc71225fa6a8e616a Mon Sep 17 00:00:00 2001 From: Robert Love Date: Fri, 6 Jul 2012 10:40:20 -0700 Subject: [SCSI] fcoe: Remove redundant 'less than zero' check strtoul returns an 'unsigned long' so there is no reason to check if the value is less than zero. strtoul already checks for the '-' character deep in its bowels. It will return an error if the user has provided a negative value and fcoe_str_to_dev_loss will return that error to its caller. This patch fixes the following Coverity reported warning: CID 703581 - NO_EFFECT Unsigned compared against 0 - This less-than-zero comparison of an unsigned value is never true.
