Subject: [PATCH 1/2] mt76: mt7615: fix .add_beacon_offload()
Date: Sun, 4 Apr 2021 15:48:23 +0800	[thread overview]
Message-ID: <e4f7df8a29d59656cff1c24dce0c2b695436e9f9.1617522253.git.ryder.lee@mediatek.com> (raw)

ieee80211_beacon_get_template() returns NULL when beacon state is disabled,
so beacon_offload cannot be disabled for some devices.
