From 9ef7223058a44990dc4650ecb1209c97ceb636b3 Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Tue, 30 May 2017 10:30:40 -0700 Subject: notes: make get_note return pointer to struct object_id Make get_note return a pointer to a const struct object_id. Add a defensive check to ensure we don't accidentally dereference a NULL pointer.
