If I follow the code correctly this init_cfg() is called whenever the device is opened, right?
This means that the format will be reset to default values every time the userspace opens the device.
So I wonder if this is what we really want, or do we want to keep the last set format instead. For
example if we use media-ctl only to get the current format, this is already enough - it opens the
subdev node and resets the format to default.
