From 107fb59e84b12bbf6bdfdd4fc241dbcda7332706 Mon Sep 17 00:00:00 2001 From: Pau Espin Pedrol Date: Wed, 15 Aug 2018 14:11:22 +0200 Subject: Drop gprs_msgb_resize_area with libosmocore replacement gprs_msgb_resize_area was introduced in libosmocore 0.94 (f78ec5ce0d0f6038147d9b9e14d81094309ba5d5) as msgb_resize_area. Let's use that one to avoid code duplication.
