Subject: [PATCH 04/11] media: exynos4-is: Correct missing entity function initialization

Commit bae4500399c4 ("[media] exynos4-is: Add missing entity function
initialization") tried to suppress the warnings such as

s5p-fimc-md camera: Entity type for entity FIMC.0 was not initialized!

However, this didn't work in all cases. Correct this by calling the set
function earlier.

Fixes: bae4500399c4 ("exynos4-is: Add missing entity function initialization")

Thank you for the patch. Please see my comments inline.

Isn't vfd->entity above a different entity than sd->entity below? If so,
this line must stay.

My understanding is that this is the capture subdev and not the scaler.
Looking at the other drivers, MEDIA_ENT_F_PROC_VIDEO_PIXEL_FORMATTER
could be the right function to use here.

Best regards,

I think we should leave above line as is, or perhaps change the function
to MEDIA_ENT_F_PROC_VIDEO_COMPOSER and...

...also add an assignment like this.

vfd->entity and sd->entity are different entities, vfd->entity corresponds to
the capture video node and sd->entity is the capture subdevice media entity.

Scaling can also be configured on that subdev, actually both functions would
be valid.

Whoops, I totally misinterpreted the fact that they are different entities. For v2
I'll remove the removal from vfd and just add MEDIA_ENT_F_PROC_VIDEO_SCALER to the sd
entity.
