From 246ad56e25b4005648cd54e0f0ab8f0357f8a42a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 10 Oct 2016 12:09:52 +0200 Subject: mac80211_hwsim: make multi-channel ops const Instead of building the multi-channel ops at runtime, declare the common ops with a macro and build both that way, so that the multi-channel ops can also be const. As a side effect, due to the removed code, this decreases the size of the module (while shifting data from .bss to .text due to the newly added const).
