From d7a92e9cb22497562b1632aebc0d625b17bbfd51 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 26 Jul 2023 09:59:52 +0300 Subject: [PATCH] fdt: off by one in ofnode_lookup_fdt() The "oftree_count" is the number of entries which have been set in the oftree_list[] array. If all the entries have been initialized then this off by one would result in reading one element beyond the end of the array.
