Subject: [PATCH] drm/rcar-du: Fix return value check in
 rcar_du_lvdsenc_get_resources()

In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR(). Also remove the dev_err call to avoid redundant
error message.
