From 3b9cf7905fe3ab35ab437b5072c883e609d3498d Mon Sep 17 00:00:00 2001 From: Stefan M Schaeckeler Date: Mon, 21 May 2018 16:26:14 -0700 Subject: [PATCH] of: unittest: for strings, account for trailing \0 in property length field For strings, account for trailing \0 in property length field: This is consistent with how dtc builds string properties. Function __of_prop_dup() would misbehave on such properties as it duplicates properties based on the property length field creating new string values without trailing \0s.
