[PATCH] ASoC: cs4265: Fix the duplicated control name
From: Fabio Estevam festevam@denx.de
Currently, the following error messages are seen during boot:
asoc-simple-card sound: control 2:0:0:SPDIF Switch:0 is already present cs4265 1-004f: ASoC: failed to add widget SPDIF dapm kcontrol SPDIF Switch: -16
Quoting Mark Brown:
"The driver is just plain buggy, it defines both a regular SPIDF Switch control and a SND_SOC_DAPM_SWITCH() called SPDIF both of which will create an identically named control, it can never have loaded without error. One or both of those has to be renamed."
Rename it from "SPDIF Switch" to "SPDIF" to avoid the name confict.

Looking through the code I think its probably better to combine the two controls here. It looks like you would need to set both to enable the SPDIF and I don't really see any reason for them to be different. I think you can just move the register bits onto the DAPM widget and have DAPM control them.
This patch also probably needs a fixes tag:
Fixes: f853d6b3ba34 ("ASoC: cs4265: Add a S/PDIF enable switch")
Apologies for missing this in my review of the original patch. Let me know if you want me to have a bash at combining them.
Thanks, Charles

Do you mean something like this?

Yeah that is almost exactly what I meant. Only thing is you don't need to put the register on the both SOC_DAPM_SINGLE and on the SND_SOC_DAPM_SWITCH. Little bit of a judgement call on which of the two to put it on.
Putting it on the SOC_DAPM_SINGLE is much closer to the existing code.
But putting it on the SND_SOC_DAPM_SWITCH feels more correct to me, ie. only enabling it when the SPDIF is in use. I would suggest this way, as the existing code is clearly not tested so it doesn't feel very valuable to stick to what the existing code does and this seems more correct.
Thanks, Charles
