This is a bit confusing, since in the next patch you say in the commit log:

- the s_crop() call was removed, judged not working
(see what happens soc_camera_s_crop() when get_crop() == NULL)

So the set_crop removal isn't temporary after all? It isn't added back in
this patch series.

Note that I am OK with removing set_crop if it never worked reliably, but
then the commit log of this patch should be updated to reflect that.

Regards,

Hans
