From: Qiushi Wu <wu000273@xxxxxxx>
kobject_init_and_add() takes reference even when it fails.
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object.
Because function omap_dss_put_device() doesn't handle dssdev->kobj,
thus we need insert kobject_put() to clean up the kobject,
when kobject_init_and_add() fails.
Fixes: f76ee892a99e ("omapfb: copy omapdss & displays for omapfb")
