The 'pix->width' field may be updated in mx3_camera_set_fmt() to fulfill the IPU stride line alignment requirements. If this update takes place, the 'fmt.pix.sizeimage' field in the struct v4l2_format stucture returned by VIDIOC_S_FMT is wrong. We need to update the 'pix->sizeimage' field in the mx3_camera_set_fmt() function to fix this issue.
