Subject: [PATCH 3.18 41/85] drm/radeon: fix mode_valids return type

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Luc Van Oostenryck <luc.vanoostenryck@...il.com>

[ Upstream commit 7a47f20eb1fb8fa8d7a8fe3a4fd8c721f04c2174 ]

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.
