[PATCH] staging: olpc_dcon: Do not call platform_device_unregister() in dcon_probe()

[Jing Xiangfeng]

In dcon_probe(), when platform_device_add() failes to add the device,
it jumps to call platform_device_unregister() to remove the device,
which is unnecessary. So use platform_device_put() instead.
