The sensor driver sets mbus format colorspace information and sizes, but not ycbcr encoding, quantization and xfer function. 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 <jacopo+renesas@jmondi.org> --- drivers/media/i2c/ov7670.c | 4 ++++ 1 file changed, 4 insertions(+)
