From 683b6d3b31a51956ea540df00abb0b78894924c1 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 8 Nov 2012 21:25:48 +0100 Subject: cfg80211: pass a channel definition struct Instead of passing a channel pointer and channel type to all functions and driver methods, pass a new channel definition struct. Right now, this struct contains just the control channel and channel type, but for VHT this will change. Also, add a small inline cfg80211_get_chandef_type() so that drivers don't need to use the _type field of the new structure all the time, which will change.
