From 091686d3b5569d2ec76b9e6dab7f3608b6f64497 Mon Sep 17 00:00:00 2001 From: Amit Arora Date: Fri, 19 May 2006 16:14:50 -0700 Subject: [PATCH] [SCSI] Return -EINVAL when "id == max_id" in scsi_scan_host_selected() The scsi_scan_host_selected() should return -EINVAL when the id is equal to the max_id. Currently it uses ">" when comparing with max_id, and hence leaves the border case when "id==max_id". The channel and lun have values valid from 0 up to, and including, max_channel or max_lun. But, the valid values for id range from 0 to max_id-1. This patch fixes the problem.
