From: Chris Lew <clew@xxxxxxxxxxxxxx>
The device release function is set before registering with rpmsg. If
rpmsg registration fails, the framework will call device_put(), which
invokes the release function. The channel create logic does not need to
free rpdev if rpmsg_register_device() fails and release is called.
