From 72dfd437995cd5af6da6d8701e81c984744bc5ae Mon Sep 17 00:00:00 2001 From: Max Date: Tue, 4 Dec 2018 11:24:18 +0100 Subject: Allow log_init() with NULL log_info Since we have library-internal categories we don't have to force application to supply its own categories. This is especially useful for testing code inside libosmocore which only use internal categories anyway.
