Subject: [PATCH v1 09/19] drm/panel: jdi: use DRM_DEV*
Date:   Thu, 31 Jan 2019 20:26:09 +0100
Message-Id: <20190131192619.9763-10-sam@ravnborg.org>
In-Reply-To: <20190131192619.9763-1-sam@ravnborg.org>
References: <20190131192619.9763-1-sam@ravnborg.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Introduce use of DRM_DEV* for logging.
This makes logging in the drm subsystem more consistent.
