From 16301861004e50be9c47113cceca62f56516a9a2 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Tue, 28 Oct 2014 18:21:18 +0100 Subject: [PATCH] mac802154: declare struct ieee802154_ops as const The ieee802154_ops structure should be never changed during runtime. This patch declare this structure as const to avoid a runtime change.
