When building ALSA as modules: drivers/built-in.o: In function `omapdss_hdmihw_remove': omap_hwspinlock.c:(.text+0x23da8): undefined reference to `snd_soc_unregister_codec' drivers/built-in.o: In function `omapdss_hdmihw_probe': omap_hwspinlock.c:(.text+0x24248): undefined reference to `snd_soc_register_codec' (the filename is inaccurate). This happens because drivers/video/omap2/dss/hdmi.c is built-in and uses ASoC services, but ASoC and ALSA are modular. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
