Subject: [PATCH] imx-drm: imx-tve: Remove unneeded check for platform_get_resource()

From: Fabio Estevam <fabio.estevam@...escale.com>

As devm_ioremap_resource() is used on probe, there is no need to explicitly 
check the return value from platform_get_resource(), as this is something that
devm_ioremap_resource() takes care by itself.
