The driver depends on SND, SND_SOC and TTY, but can't be selected individually, only via its user. Then, it usually builds when CONFIG_SND_SOC_OMAP_AMS_DELTA=y, and that's probably uncommon due to specific dependencies. However, cx20442 can also be selected and built with CONFIG_COMPILE_TEST=y and CONFIG_SND_SOC_ALL_CODECS=y. Since similar approach seems to apply to quite a number of ASoC CODECs, maybe build-bots should pay special attention to select SND_SOC_ALL_CODECS more frequently, like they probably do with COMPILE_TEST.
