From 1809510715c4187fa7338204cac53e30326d5d04 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 6 Aug 2015 09:25:57 -0300 Subject: [media] media: get rid of unused "extra_links" param on media_entity_init() Currently, media_entity_init() creates an array with the links, allocated at init time. It provides a parameter (extra_links) that would allocate more links than the current needs, but this is not used by any driver. As we want to be able to do dynamic link allocation/removal, we'll need to change the implementation of the links. So, before doing that, let's first remove that extra unused parameter, in order to cleanup the interface first.

So, we need to use a better name for the function that create links between two pads. So, rename the such function to media_create_pad_link(). No functional changes.

This does not work now that object IDs are used to create links so the media_device has to be set. Split out the pads links creation from the entity initialization so the links are created after the entities have been registered with the media device.

Basically, it does a logical or of this macro, in order to check for a local index and if the entity is either a subdev or not. As we'll get rid of MEDIA_ENT_T_V4L2_SUBDEV macro, replace it by 2 << 16 where it occurs, and add a note saying that the code there is actually a hack.

However, certain devices, like a FLASH led/light doesn't have any input or output PAD. So, there's no reason why calling media_entity_init() would be mandatory. Also, despite its name, what this function actually does is to initialize the PADs data. So, rename it to media_entity_pads_init() in order to reflect that. The media entity actual init happens during entity register, at media_device_register_entity(). We should move init of num_links and num_backlinks to it.

Also, since the only possible failure for the link creation is a memory allocation, there is no need for error messages since the core already reports a very verbose message in that case.
