From 4c94e37453ea293ab3196bed6d2b1b0e733518f0 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 27 Jun 2022 12:49:03 +0200 Subject: [PATCH] wifi: cfg80211: remove chandef check in cfg80211_cac_event() commit d6f671c8a339d5b655acfacb8be6918c744fbabf upstream. The current check only worked for AP mode, but we can do radar detection in mesh as well (for example). We could try to check this using wdev_chandef(), but we also don't really care since the chandef is passed in and we have no need to use it anymore (since we added the argument in commit d2859df5e7f0 ("cfg80211/mac80211: DFS setup chandef for cac event")).
