Thanks for pointing this out - I had also a closer look at the codecs and the 
other FSI related codec (da7210.c) depends on I2C too.

So maybe even move the dependency up to SND_SOC_SH4_FSI 
since both codecs rely on I2C?

So something like this would be more appropriate?
 config SND_SOC_SH4_FSI
 	tristate "SH4 FSI support"
+	depends on CONFIG_I2C_SH_MOBILE
 	help
 	  This option enables FSI sound support

If you think this patch sounds correct, I can create a new 'official' patch.
