From 74b6bda32f8350b2dc32f8d66f4046272168184e Mon Sep 17 00:00:00 2001 From: René Scharfe Date: Wed, 28 Mar 2018 23:14:08 +0200 Subject: submodule: check for NULL return of get_submodule_ref_store() If we can't find a ref store for a submodule then assume the latter is not initialized (or was removed). Print a status line accordingly instead of causing a segmentation fault by passing NULL as the first parameter of refs_head_ref().
