[PATCH v4 2/3] firmware: edd: Fix kobject reference leak on registration failure

[Tarun Sahu]

Per kobject_init_and_add() kernel-doc, calling kfree() directly on
error bypasses reference counting and skips the kobject's release
callback, leaking the reference.

Use kobject_put() instead of kfree() on registration failure to fix
this.
