[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. "*val < 0UL". drivers/scsi/fcoe/fcoe_sysfs.c:105 Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
