Subject: [PATCH 04/14] drm/panel-leadtek-ltk050h3146w: Drop custom DSI write macro
Date:   Wed, 28 Dec 2022 02:47:47 +0100
Message-Id: <20221228014757.3170486-5-javierm@redhat.com>
In-Reply-To: <20221228014757.3170486-1-javierm@redhat.com>

Precedence: bulk

There is a macro for this already in the <drm/drm_mipi_dsi.h> header, use
that instead and delete the custom DSI write macro defined in the driver.
