With commit e2329eeba45f ("ASoC: soc-component: add soc_component_err()") every error different for ENOTSUPP or EPROBE_DEFER will log an error.

However, as explained in snd_soc_get_dai_name(), this callback may error to indicate that the DAI is not matched by the component tested. If the device provides other components, those may still match. Logging an error in this case is misleading.

Don't use soc_component_ret() in snd_soc_component_of_xlate_dai_name() to avoid spamming the log.

If we wish to report an error when no name is found for dai phandle, I think it would be more approriate to it with with "struct device *" of the card, which is the one actually failing to get what it needs.

These user of snd_soc_get_dai_name() are already reporting the error: * sound/soc/samsung/tm2_wm5110.c * sound/soc/rockchip/rk3288_hdmi_analog.c

These could be silently failing: * Simple cards * Amlogic's cards * Samsumg odroid card
