From d51b720fca4ee5418952a90f785317592a7a1242 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Thu, 15 Sep 2011 23:10:38 +0200 Subject: [PATCH] remote: avoid passing NULL to read_ref() read_ref() can (and in test t5800, actually *does*) return NULL. Don't pass the NULL along to read_ref(). Coincidentally, this mistake didn't make resolve_ref() blow up, but upcoming changes to resolve_ref() will make it less forgiving.
