Subject: [PATCH 02/10] Bluetooth: rfcomm: remove casts from tty->driver_data
Date:   Mon, 31 Jul 2023 10:02:36 +0200
Message-ID: <20230731080244.2698-3-jirislaby@kernel.org>
In-Reply-To: <20230731080244.2698-1-jirislaby@kernel.org>

Precedence: bulk

tty->driver_data is 'void *', so there is no need to cast from that.
Therefore remove the casts and assign the pointer directly.
