From 8b174c4735517c2262d6a992d92e93bba005e8a8 Mon Sep 17 00:00:00 2001 From: Sebastian Kemper Date: Mon, 20 Nov 2017 12:24:35 +0100 Subject: [PATCH] chan-lantiq: pull the source from github Instead of using local copies pull the source from github. The source version is selected via CHAN_LANTIQ_VERSION, so there can be a different version for each VARIANT.
