Subject: [PATCH] driver core: platform: remove misleading err_alloc label

From: Johannes Berg <johannes.berg@...el.com>

In platform_device_register_full() the err_alloc label is
misleading, we only ever jump to it if the pdev is NULL,
but it then proceeds to free it, which is a no-op.

Remove the label and simply exit the function immediately.
