[PATCH 1/4] media: staging: rkisp1: remove two unused fields in uapi struct

[Ezequiel Garcia]

Hi Dafna,

Thanks for all the rkisp1 patches, I hope we can get
the driver out of staging soon.

If I understand correctly, you are affecting the uAPI here.

The fact that the driver doesn't use it now, doesn't mean
it won't need it at some later point.

I'm not saying the change is wrong, but that the "not currently
in use" reason might be insufficient for a uAPI. If you
want to remove this field, I suggest you make sure
the field is inappropriate for this interface.

Also, it would be better if you could add a cover letter
on all the series, there are a bunch of rkisp1 patches now
and having a cover letter helps by adding some context.

Thanks,
Ezequiel
