When supplied with an badly initialized mbus frame format structure, those fields need to be set explicitly not to leave them uninitialized. This is tested by v4l2-compliance, which supplies a mbus format description structure and checks for all fields to be properly set. Without this commit, v4l2-compliance fails when testing formats with: fail: v4l2-test-formats.cpp(335): ycbcr_enc >= 0xff Signed-off-by: Jacopo Mondi --- drivers/media/i2c/ov7670.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/media/i2c/ov7670.c b/drivers/media/i2c/ov7670.c index 25b26d4..61c472e 100644 --- a/drivers/media/i2c/ov7670.c +++ b/drivers/media/i2c/ov7670.c @@ -996,6 +996,10 @@ static int ov7670_try_fmt_internal(struct v4l2_subdev *sd, fmt->height = wsize->height; fmt->colorspace = ov7670_formats[index].colorspace; + fmt->ycbcr_enc = V4L2_YCBCR_ENC_DEFAULT; + fmt->quantization = V4L2_QUANTIZATION_DEFAULT; + fmt->xfer_func = V4L2_XFER_FUNC_DEFAULT; + info->format = *fmt; return 0;
