Subject: [PATCH v7 05/13] drm/panel: st7703: Rename functions from jh057n prefix to st7703
Date:   Wed,  1 Jul 2020 18:29:20 +0200
Message-Id: <20200701162928.1638874-6-megous@megous.com>
In-Reply-To: <20200701162928.1638874-1-megous@megous.com>

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This is done so that code that's not specific to a particular
jh057n panel is named after the controller. Functions specific
to the panel are kept named after the panel.
