Subject: [PATCH net v2 01/21] net: set .owner to THIS_MODULE

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

Fixes: 9e466250ede3 ("batman-adv: Prefix bat_debugfs local static functions with batadv_")
Fixes: 5609c185f24d ("6lowpan: iphc: add support for stateful compression")
Signed-off-by: Taehee Yoo <ap420073@...il.com>
