Hi, I request support for the number board of my SAA7130 (philips
semiconductor chipset) with fmradio card because it isn't listed in
the v4l2 driver list of Saa7134 module. The Tuner card is Winstars
WS-TVP7130FM.
the output of dmesg command is:

When setting a control directly on a subdev node the VSP1 driver doesn't
guarantee that the device is powered on. This leads to crashes when the
control handlers writes to hardware registers. One easy way to fix this
is to ensure that the device gets powered on when a subdev node is
opened. However
The VSP1 stores the video pipelines' input (RPF) to output (WPF)
mappings in a WPF register. An RPF must never be associated with
multiple WPFs, even if all of those WPFs but one are unused, otherwise
the hardware won't function properly.
The driver doesn't ensure this correctly as it never clears

If bytesused is not populated, it means bytesused is same as length.
