As we don't need anymore to share pad numbers with similar
drivers, use its own pad definition instead of a global
model.

Except for DVB, all media kAPI headers are at include/media.
Move the headers to it.

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.

Move the au8522_media_pads enum to au8522.h from au8522_priv.h to export
them. This will allow au0828-core to use these defines instead of
hard-coding them them.

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.

The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.
So, let's do it.
This patch was generated by this shell script:
for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done
While here, make CodingStyle fixes on the affected lines.

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.
