Subject[PATCH 3.18 18/85] ARM: davinci: board-dm355-evm: fix broken networking
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

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

From: Sekhar Nori <nsekhar@ti.com>

[ 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.

Fixes: 09f3756bb9a8 ("dm9000: Return an ERR_PTR() in all error conditions of dm9000_parse_dt()")
