Subject: [PATCH] drm/gma500: fix mode_valid's return type
Date:   Tue, 24 Apr 2018 15:14:54 +0200
Message-Id: <20180424131455.2011-1-luc.vanoostenryck@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The method struct drm_connector_helper_funcs::mode_valid is defined
as returning an 'enum drm_mode_status' but the driver implementation
for this method uses an 'int' for it.

Fix this by using 'enum drm_mode_status' in the driver too.
