From cc66880ba58ef6b9ee645fa1e1c074746ff03ce4 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 16 May 2012 16:37:57 +0200 Subject: [PATCH] iwlwifi: use mac80211 channel for radar check In channel switch, instead of relying on our internal channel database, just use the mac80211 channel that we filled with that information on startup.
