From: Ding Xiang <[email protected]> commit 961b6ffe0e2c403b09a8efe4a2e986b3c415391a upstream.
In the error path of stm_source_register_device(), the kfree is unnecessary, as the put_device() before it ends up calling stm_source_device_release() to free stm_source_device, leading to a double free at the outer kfree() call. Remove it.
