From 856a4ef9f01e9f4b42c96dd70268f4864a93f72c Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 29 Oct 2013 19:34:26 +0100 Subject: [PATCH] rtlwifi: fix usage of freq_reg_info() freq_reg_info() expects KHz and not MHz, fix this. In this case we'll now be getting the no-ir flags cleared on channels for any channel when the country IE trusts that channel. @@ struct ieee80211_channel *ch; struct wiphy *wiphy; const struct ieee80211_reg_rule *rule; @@ -rule = freq_reg_info(wiphy, ch->center_freq); +rule = freq_reg_info(wiphy, MHZ_TO_KHZ(ch->center_freq)); Generated-by: Coccinelle SmPL Cc: Julia Lawall Cc: Peter Senna Tschudin Cc: Larry Finger Reported-by: Mihir Shete Signed-off-by: Luis R.
