As we want au0828 to use the core function to create the MC
graphs, use enum demod_pad_index instead of
enum au8522_media_pads.

With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. 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.

Entities should have one or more functions. Calling it as a
type proofed to not be correct, as an entity could eventually
have more than one type.
So, rename the field as function.
Please notice that this patch doesn't extend support for
multiple function entities. Such change will happen when
we have real case drivers using it.
No functional changes.

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.

Checking where the error happens:
(gdb) list *au8522_probe+0x19a
0x99a is in au8522_probe (drivers/media/dvb-frontends/au8522_decoder.c:761).
756 printk(KERN_INFO "au8522_decoder attach existing instance.\n");
757 break;
758 }
759
760 demod_config = kzalloc(sizeof(struct au8522_config), GFP_KERNEL);
761 if (demod_config == NULL) {
762 if (instance == 1)
763 kfree(state);
764 return -ENOMEM;
765 }
Shows that the error path is not being handled properly.
The are actually several issues here:
1) config free should have been calling hybrid_tuner_release_state()
function, by calling au8522_release_state();
2) config is only allocated at the digital part. On the analog one,
it is received from the caller.
A complex logic could be added to address it, however, it is simpler
to just embeed config inside the state.

There are several issues on the current code:
1) msleep(1) is actually equivalent to msleep(10);
2) au8522_video_set() will set reg 0xa4 to the
proper value for SIF, CVBS or S-Video. No need
to force it to CVBS;
3) Let's not hardcode 0x9d for CBS on audio_set.

setup_decoder_defaults() doesn't really care about the input
port. All it needs to know is if the input port is s-video or
not.
As the caller function already knows that, just pass a boolean
instead.

Let's set the the audio routing also at stream start. With this change,
we don't risk enabling the analog demux while not streaming, reducing
the risk of interfering with a DVB demux that might be happening.

The same demod is used on both analog and digital mode. We should
not let the commands for analog mode to happen while the device
is in digital mode. So, monitor it via streamon.

The input mode is used not only inside the setup_decoder_defaults()
but also at au8522_*_mode routines.
So, move it one level up. As an advantage, we can now group the
function that sets the input into just one.
