2016-09-09[media] demux.h: fix a documentation warningMauro Carvalho Chehab1-3/+5

2016-09-06[media] pulse8-cec: sync configuration with adapterJohan Fjeldtvedt1-38/+228
When the configuration is changed, they are also written to the adapter. This allows the adapter to continue operating in autonomous mode with the same settings when it is disconnected from the driver (typically by going into suspend). For adapters with firmware version 2 or greater, the settings are also persisted in EEPROM. A new module parameter is added to optionally also use the configuration already present in the adapter when it is connected. This option is enabled by default. When a new configuration is written, the autonomous mode is automatically enabled. When the device is unconfigured, autonomous mode is disabled.

With the current settings, only one channel locks properly. That's likely because, when this driver was written, Brazil were still using experimental transmissions.

2016-09-05[media] mb86a20s: fix the locking logicMauro Carvalho Chehab1-1/+11
On this frontend, it takes a while to start output normal TS data. That only happens on state S9. On S8, the TS output is enabled, but it is not reliable enough. However, the zigzag loop is too fast to let it sync. As, on practical tests, the zigzag software loop doesn't seem to be helping, but just slowing down the tuning, let's switch to hardware algorithm, as the tuners used on such devices are capable of work with frequency drifts without any help from software.

implementation * Reuse existing functionality from memdup_user() instead of keeping duplicate source code. This issue was detected by using the Coccinelle software. * Return directly if this copy operation failed. * Replace the specification of data structures by pointer dereferences to make the corresponding size determination a bit safer according to the Linux coding style convention.

2016-08-24[media] v4l2-async: remove unneeded .registered_async callbackJavier Martinez Canillas1-7/+0
The v4l2_subdev_core_ops .registered_async callback was added to notify a subdev when its entity has been registered with the media device, to allow for example to modify the media graph (i.e: adding entities/links). But that's not needed since there is already a .registered callback in struct v4l2_subdev_internal_ops that's called after the entity has been registered with the media device in v4l2_device_register_subdev().

2016-08-24[media] tvp5150: use sd internal ops .registered instead .registered_asyncJavier Martinez Canillas1-2/+6
The driver is using the struct v4l2_subdev_core_ops .registered_async callback to register the connector entities and create the pad links after the subdev entity has been registered with the media device. But the .registered_async callback isn't needed since the v4l2 core already calls the struct v4l2_subdev_internal_ops .registered callback in v4l2_device_register_subdev(), after media_device_register_entity(). So, use the .registered() callback instead of the .registered_async() that is going to be removed in a following patch since isn't needed.

2016-08-24[media] v4l: Do not allow re-registering sub-devicesSakari Ailus1-4/+1
Albeit not prohibited explicitly, re-registering sub-devices generated a big, loud warning which quite likely soon was followed by a crash. What followed was re-initialising a media entity, driver's registered() callback being called and re-adding a list entry to a list. Prevent this by returning an error if a sub-device is already registered.
