Subject: [PATCH 13/15] wifi: iwlwifi: mvm: Do not warn on invalid link on scan complete
Date: Tue, 19 Mar 2024 10:10:25 +0200	[thread overview]
Message-ID: <20240319100755.619d3574a757.I0523e92547f0288c8b0119b1fdc5e967a5a8956e@changeid> (raw)
In-Reply-To: <20240319081027.3853611-1-miriam.rachel.korenblit@intel.com>

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

As it is possible that by the time the scan is completed the link was
already removed.
