From 3fd654c22c7b002e8681accaed50a6d46656d815 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 29 Mar 2012 21:52:57 +0300 Subject: [PATCH] Staging: rts_pstor: off by one in for loop I already fixed the other similar for loop in this file. I'm not sure how I missed this one. We use seg_no+1 inside the loop so we can't go right up to the end of the loop. Also if we don't break out of the loop then we end up past the end of the array, but with this fix we end up on the last element.
