If anyone has any objections, please let me know. ------------------ From: Sekhar Nori [ Upstream commit 5c054de228dd6d97bf8e38962bd118953b66e5a0 ] Since commit 09f3756bb9a8 ("dm9000: Return an ERR_PTR() in all error conditions of dm9000_parse_dt()"), passing either non-NULL platform data or device-tree for dm9000 driver to probe is mandatory. DM335 board was using none, so networking failed to initialize. Fix it by passing non-NULL (but empty) platform data.
