I'm not sure I fully understand what you mean.

The Kconfig entry for the CODEC has no 'depends on'. It does a 'select 
SND_SOC_AC97_BUS', which means all built time dependencies are pulled in 
this way. So if SND_SOC_ALL_CODECS selects the CODEC unconditionally that 
should work fine, since no dependencies are bypassed.
