Subject: [PATCH AUTOSEL 4.19 15/28] net: ieee802154: stop dump llsec devs for monitors
Date: Mon, 12 Apr 2021 12:25:40 -0400 [thread overview]
Message-ID: <20210412162553.315227-15-sashal@kernel.org> (raw)
In-Reply-To: <20210412162553.315227-1-sashal@kernel.org>
From: Alexander Aring <aahringo@redhat.com>
[ Upstream commit 5582d641e6740839c9b83efd1fbf9bcd00b6f5fc ]
This patch stops dumping llsec devs for monitors which we don't support
yet. Otherwise we will access llsec mib which isn't initialized for
monitors.
