Subject: [PATCH 4.9 22/42] batman-adv: set .owner to THIS_MODULE
Date: Tue,  1 Dec 2020 09:53:20 +0100	[thread overview]
Message-ID: <20201201084643.775611464@linuxfoundation.org> (raw)
In-Reply-To: <20201201084642.194933793@linuxfoundation.org>

From: Taehee Yoo <ap420073@gmail.com>

[ Upstream commit 14a2e551faea53d45bc11629a9dac88f88950ca7 ]

If THIS_MODULE is not set, the module would be removed while debugfs is
being used.
It eventually makes kernel panic.

Fixes: c6c8fea29769 ("net: Add batman-adv meshing protocol")
