[alsa-devel] [PATCH] ASoC: tpa61xx: add back chip name to the controls
Commit cb7e62256e99( ASoC: tpa6130a2: Register component) removed the chip name from the controls, which causes issues as the TPA61xx is not a standalone codec, but a headphone amplifier, which may be connected to the line out of a codec which already exposes a "Headphone Playback Volume" control. In that case we end up with duplicate controls, causing the the probe of the soundcard to be aborted.

In this case the intention is that the machine driver should add a prefix via name_prefix in a struct snd_soc_codec_conf.

Thanks for the pointer. In my case the machine driver is the simple-card. I'll have a look at how I can get the prefix hooked up there. Regards, Lucas
