GStreamer is also using Video4Linux API btw (hence the name of the element). It
looks like GStreamer expects a certain ioctl() to be supported, but it's not
supported by your driver. I don't own any FM radio device supported by
linux/v4l2 myself, so I can't try and reproduce your issue (need to ask Hans if
we have an emulated driver somewhere).

Though, I can guide you through if you are able to provide more information.
First step you be to produce a v4l2 log.

GST_DEBUG="v4l2*:7" gst-launch v4l2radio device=/dev/radio0 frequency=101200000

This should give us more context around this failure.
