[v3,10/14] media: platform: pxa_camera: remove set_crop
Commit Message
This is to be seen as a regression as the set_crop function is
removed. This is a temporary situation in the v4l2 porting, and will
have to be added later.

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

Well, it's temporary in the sense "I have not added it back yet, but I commit to
add it back within 2 or 3 kernel cycles"
As for the confusion, I think the pxa_camera + mt9m111 set_crop() was not
working, but I didn't say that another camera host + mt9m111 didn't work. I
think set_crop() is not working because pxa_camera lacks code, but that doesn't
prevent mt9m111 to have a set_crop() sensor working implementation.
That's why I say I'm probably adding a regression, and commit to remove it soon
...
Cheers.
