Sorry, that was an ASoC board driver, not a CODEC driver, that required the
fix.

In addition to SOUND, SND, SND_SOC and TTY, this ASoC board driver depends
on MACH_AMS_DELTA, then on ARM, MMU, ARCH_MULTI_V4T, !ARCH_MULTI_V6,
!ARCH_MULTI_V7, CPU_LITTLE_ENDIAN, ATAGS, ARCH_OMAP1 and ARCH_OMAP15XX.
Let me check if it builds without those machine dependencies, then we can
cover it by COMPILE_TEST.
Thanks,
