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.
