Now I notice that this test is not so useful for this conversion.
Maybe I will change the colors of the test to stop the expected
array from being just zeros on the v2.

I've posted a v2 since the kernel robot found a build warning on v1:

https://lists.freedesktop.org/archives/dri-devel/2023-March/394473.html

This time I have also tested your patch rebased on top of my v2, and
your tests are passing too:

I don't think you need a new helper only for this. There are other
formats that have sub-byte pixels, so you may want to instead make
the existing conversion_buf_size() function more general.

Could you please base on the following patch that I just posted?

https://lists.freedesktop.org/archives/dri-devel/2023-March/394466.html

I believe with that you should be able to drop this format specific
helper and just use the fourcc DRM_FORMAT_C1 instead.

Then here you could just do:

dst_size = conversion_buf_size(DRM_FORMAT_C1, result->dst_pitch,
   >clip);

If you do that, feel free to add:
