From 55b183ad8635589ea731a31653de79a2626491c4 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 11 Jan 2013 14:22:58 +0100 Subject: [PATCH] wireless: fix regulatory HT40 allowed check commit 1a9193185f462a51815fe48491f8a6fb6b942551 "regulatory: code cleanup" changed is_ht40_allowed without considering that IEEE80211_CHAN_NO_HT40 is not just one flag, but two. This is causing HT40- to be blocked completely.
