From ea1fdbe6f81fa1cc647ccc426a0e9165b628cbdc 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 5ff89456a68893437d1e697b3fc012bad304228f "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.
