[PATCH v2 1/4] staging: vc04_services: Stop leaking platform device on error path

[Umang Jain]

vchiq driver registers the child platform devices in
vchiq_register_child(). However, in the registration error code path,
currently the driver is leaking platform devices by not destroying the
return platform device. Plug this leak using platform_device_put() as
mentioned in the documentation for platform_device_register().
