Subject: [PATCH 09/13] cfg80211: Save the regulatory domain when setting custom regulatory
Date: Sun, 29 Nov 2020 17:30:51 +0200	[thread overview]
Message-ID: <iwlwifi.20201129172929.290fa5c5568a.Ic5732aa64de6ee97ae3578bd5779fc723ba489d1@changeid> (raw)
In-Reply-To: <20201129153055.1971298-1-luca@coelho.fi>

From: Ilan Peer <ilan.peer@intel.com>

When custom regulatory was set, only the channels setting was updated, but
the regulatory domain was not saved. Fix it by saving it.
