commit cdd0f118ef87db8a664fb5ea366fd1766d2df1cd upstream.
vpu_get_plat_device() increases the reference count of the returned
platform device. However, when devm_kzalloc() fails, the reference
is not released, causing a reference leak.
Fix this by calling put_device() on fw_pdev->dev before returning
on the error path.
