am i doing something wrong or are the dev_* output functions kind of useless with ASoC codecs ? it seems like the error output is prefixed by the generic "soc-audio" but no info related to the exact codec is included.
as an example, the typical behavior is for the machine driver to call platform_device_alloc("soc-audio", -1). this struct device is then passed down to the relevant subsystem driver register/probe (i2c/spi/etc...) to the codec driver. these functions typically then set the snd_soc_codec's dev member to the allocated platform device. which means the snd_soc_codec's name member isnt included in decoding. so now any dev_* output in the codec driver looks like: soc-audio soc-audio: some message
if there are multiple codecs, things obviously fall apart quickly. the question is how to address this. werent there snd_* output funcs before ? or are those now deprecated/dead ? or perhaps we should encourage people to stop doing platform_device_alloc("soc-audio") and start doing platform_device_alloc(snd_soc_card.name) ?
also, there seems to be a semi-common bug in the codec/machine drivers where they dont actually initialize the dev member. perhaps it's time to upgrade the snd_soc_register_codec() check from a KERN_WARNING to a BUG_ON() ? clearly the current warning isnt getting its message through ... -mike
