Subject: [PATCH 6/6] drm/i2c: tda998x: cleanup from previous changes
MIME-Version: 1.0
Content-Disposition: inline
Content-Transfer-Encoding: 8bit
Content-Type: text/plain; charset="utf-8"
Message-Id: <E1fbSCZ-000773-0U@rmk-PC.armlinux.org.uk>
Date:   Fri, 06 Jul 2018 15:59:15 +0100
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Cleanup the code a little from the effects of the previous changes:
- Move tda998x_destroy() to be above tda998x_create()
- Use 'dev' directly in tda998x_create() where appropriate.
