Subject: [PATCH net v2 07/21] wlcore: set .owner to THIS_MODULE
Date: Sat,  7 Nov 2020 17:21:38 +0000	[thread overview]
Message-ID: <20201107172152.828-8-ap420073@gmail.com> (raw)
In-Reply-To: <20201107172152.828-1-ap420073@gmail.com>

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

Fixes: f5fc0f86b02a ("wl1271: add wl1271 driver files")
Fixes: bcca1bbdd412 ("wlcore: add debugfs macro to help print fw statistics arrays")
Signed-off-by: Taehee Yoo <ap420073@gmail.com>
