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.

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

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.
