From 0796a6c0fcd31f2d52a50a1ffd699897d658b088 Mon Sep 17 00:00:00 2001 From: Alexander Chemeris Date: Tue, 11 Jul 2017 01:42:41 +0630 Subject: libcommon: Fix log output for bts>0. Fixes regression probably introduced in c696cc28. For bts>0 logging doesn't show bts number correctly when printing lchan identification string - it will always show it as "bts=0". The reason for this is that the identification string is cached before bts->nr value is set to a proper value. This patch sets bts->nr as part of the first step of the bts structure initialization, before caching happens thus making sure the cached identification string is cached with the correct values.
