From 62eb01f5c2d735e8aeab6bc95e5832cb59397527 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sat, 25 Oct 2014 09:40:59 +0200 Subject: mac802154: move ieee802154_dev.c to main.c The ieee802154_dev functionality contains various function for allocation and registration of an ieee802154_dev. This is equal to the net/mac80211/main.c file. This patch rename the ieee802154_dev.c to main.c to have the same behaviour.
