Subject: [PATCH 4.14 27/50] batman-adv: set .owner to THIS_MODULE

From: Taehee Yoo <ap420073@...il.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")
