struct v4l2_subdev.host_priv is intended to be used by another driver. This is hardly good design but back in the days of platform data was a quick hack to get things done. As the sub-device specific bus information can be stored to the ISP driver specific struct allocated along with v4l2_async_subdev, keep the information there and only there.

Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Signed-off-by: NMauro Carvalho Chehab <mchehab@s-opensource.com>

The media device node is registered and so made visible to user-space before entities are registered and links created which means that the media graph obtained by user-space could be only partially enumerated if that happens too early before all the graph has been created. To avoid this race condition, split the media init and registration in separate functions and only register the media device node when all the pending subdevices have been registered, either explicitly by the driver or asynchronously using v4l2_async_register_subdev(). The media_device_register() had a check for drivers not filling dev and model fields but all drivers in mainline set them and not doing it will be a driver bug so change the function return to void and add a BUG_ON() for dev being NULL instead. Also, add a media_device_cleanup() function that will destroy the graph_mutex that is initialized in media_device_init().

The entities to video nodes links were created on separate functions for each ISP module but since the only thing that these functions do is to call media_create_pad_link(), there's no need for that indirection level and all link creation logic can be just inlined in the caller function.

Instead of relying on media subtype, use the new macros to detect if an entity is a subdev or an A/V DMA entity. Please note that most drivers assume that there's just AV_DMA or V4L2 subdevs. This is not true anymore, as we've added MC support for DVB, and there are plans to add support for ALSA and FB/DRM too. Ok, on the current pipelines supported by those drivers, just V4L stuff are there, but, assuming that some day a pipeline that also works with other subsystems will ever added, it is better to add explicit checks for the AV_DMA stuff.

The omap3isp driver parses the graph endpoints to know how many subdevices needs to be registered async and register notifiers callbacks for to know when these are bound and when the async registrations are completed. Currently the entities pad are linked with the correct ISP input interface when the subdevs are bound but it happens before entitities are registered with the media device so that won't work now that the entity links list is initialized on device registration. So instead creating the pad links when the subdevice is bound, create them on the complete callback once all the subdevices have been bound but only try to create for the ones that have a bus configuration set during bound.

The struct media_entity has a .parent field that stores a pointer to the parent struct media_device. But recently a media_gobj was embedded into the entities and since struct media_gojb already has a pointer to a struct media_device in the .mdev field, the .parent field becomes redundant and can be removed. This patch replaces all the usage of .parent by .graph_obj.mdev so that field will become unused and can be removed on a later patch. No functional changes.
