Instead of filling in the struct v4l2_capability device_caps field, fill in the struct video_device device_caps field. That way the V4L2 core knows what the capabilities of the video device are. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> --- Hi Andrey, I noticed this new staging V4L2 driver. FYI, please CC any future patches to this driver to the linux-media@vger.kernel.org mailinglist as well so we can review it. I'll post a review of this driver later today as well. In the meantime, I'd like to get this patch in since during the upcoming 5.4 cycle we will require that the device_caps field of struct video_device is set correctly. Regards, Hans Changes since v1: - drop V4L2_CAP_TUNER since this device has no tuner. ---
