kobject (c06a4250): tried to init an initialized object, something is
seriously wrong.
introduced by commit 66293989:
(omap: convert boards that use SMSC911x to use gpmc-smsc911x)
fixed by allocating struct platform_device dynamically.
Signed-off-by: Igor Grinberg <grinberg@xxxxxxxxxxxxxx>
---
This has been boot tested with nfs root on cm-t35,
and build tested on all other affected boards.
v2: keep the id field uninitialized (0) on boards with
only one smsc911x controller (thanks Mike)
