The driver doesn't set the device in the struct v4l2_capability bus_info field so v4l2-compliance reports the following error for VIDIOC_QUERYCAP: Required ioctls: fail: v4l2-compliance.cpp(537): missing bus_info prefix ('platform') test VIDIOC_QUERYCAP: FAIL This patch fixes this by filling also the device besides the bus.
