[PATCH 1/1] v4l: subdev: Register the entity before calling subdev's registered op

2015-12-27 Thread Sakari Ailus

Registering a V4L2 sub-device includes, among other things, registering
the related media entity and calling the sub-device's registered op. Since
patch "media: convert links from array to list", creating a link between
two pads requires registering the entity first. If the registered() op
involves link creation, the link list head will not be initialised before
it is used.

Resolve this by first registering the entity, then calling its
registered() op.

Hi Mauro,

You seem to be missing this patch from your media-controller-rc4 branch.
Not having it breaks at least the smiapp driver. I was pretty sure to have
sent it but I can't find it on linux-media. Oh well.

Speaking of the entity function warnings --- I'd omit them until we've
agreed that this is what we should really have (I don't think so). I can
submit a patch to remove them if you like.
