How to using clCreateImage to create a miapmap image?

I'm trying to use clCreateImage to create a mipmap image, but returns **CL_INVALID_IMAGE_DESCRIPTOR** . Here is my code:
```
cl_image_desc clImageIn;
memset(&clImageIn, 0, sizeof(cl_image_desc));
clImageIn.image_type = CL_MEM_OBJECT_IMAGE2D;
clImageIn.image_width = 1920;
clImageIn.image_height = 1080;
clImageIn.num_mip_levels = 2;

cl_image_format clImageFormat;
clImageFormat.image_channel_order = CL_R;
clImageFormat.image_channel_data_type = CL_UNORM_INT8;

int ret;
cl_mem image = clCreateImage(context, CL_READ_ONLY, &clImageFormat, &clImageIn, NULL, ret);
```

and the ret also returns -65, is there something wrong?
Btw, I find mali-G57 cannot support OPENCL EXTENSION of _cl_khr_mipmap_image_ ,is that true?

Start with the clCreateImage API documentation and compare the shown cl_image_desc fields and return-value handling with the specification. Then check the _cl_khr_mipmap_image_ support question for Mali-G57. Done means providing a source-backed explanation of the error and the relevant mipmap support details.
