Subject: [PATCH net v2 15/21] wil6210: set .owner to THIS_MODULE
Date:   Sat,  7 Nov 2020 17:21:46 +0000
Message-Id: <20201107172152.828-16-ap420073@gmail.com>
In-Reply-To: <20201107172152.828-1-ap420073@gmail.com>
References: <20201107172152.828-1-ap420073@gmail.com>
Precedence: bulk

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