From f75c30ef084fb57d3edab6722077e0adf16ed8fd Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 5 Nov 2013 09:18:11 -0800 Subject: [PATCH] cfg80211: allow only the core to request to update the world regdom It seems some out of tree drivers were using a regulatory_hint("00") to trigger off the wiphy regulatory notifier, for those cases just setting the WIPHY_FLAG_CUSTOM_REGULATORY would suffice to call the reg_notifier() for a world regulatory domain update. If drivers find other needs for calling the reg_notifier() a proper implemenation is preferred. Signed-off-by: Luis R.
