From 7e79f78b331632c1812ce9c07443550aa2b6c0fe Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 9 Feb 2011 12:40:12 +0300 Subject: [PATCH] Staging: rts_pstor: fix read past end of buffer We read one space past the end of the buffer because we add 1. Also I changed it to use ARRAY_SIZE() instead of manually calculating the size.
