Hi,
I am trying to add support for the ADAV801 codec to my 2.6.35.3 kernel. I came across this patch http://article.gmane.org/gmane.linux.alsa.devel/86474 obviously I had to make some modifications so it would correctly patch my source. However when I come to build the kernel I'm getting a whole host of
errors
and I am little unsure on how to proceed, could anyone maybe provide some guidance on the possible causes of my errors or maybe there is a more
update
driver available.
Many thanks

Your kernel version is rather old and was before the big Multi-Component patch, which change the ASoC API quite a bit. There is an old patch[1] adding ADAV801 support which still uses the pre Multi-Component API you could use. Other options are to update your kernel to a more recent version or backport the Multi-Component patch.

I think that is it, Though the patch caused the kernel to cross compile
with error
sound/soc/codecs/adav80x.c:431:7: error: 'struct snd_soc_codec' has no member named 'private_data'
it looks as though in sound/soc.h private_data is referenced as drvdata so I have modified the patch and the kernel has now compiled successfully. I'll have to make some modifications to the kconfig as the driver will only build when SND_SOC_ALL_CODECS=y. It'll be a little while before I can test the codec on actual hardware but if I have anymore trouble I'll drop you a mail.
Thanks.
