[PATCH 3/6] ASoC: amd: SND_SOC_RT5682_I2C does not build rt5682

[RAVULAPATI, VISHNU VARDHAN RAO]

[AMD Official Use Only - Internal Distribution Only]

So Actually for rt5682 codec Now in 5.8 there are three flags :
SND_SOC_RT5682
SND_SOC_RT5682_I2C
SND_SOC_RT5682_SDW

But till 5.7.8 we have
SND_SOC_RT5682
SND_SOC_RT5682_SDW

So in our design we were using SND_SOC_RT5682 which build snd_soc_rt5682.ko
Creates the respective codec_dais as defined in that .ko

If we use SND_SOC_RT5682_I2C we get snd_soc_rt5682_I2c.ko , it is not creating the expected codec_dai links.

As there are three flags defined in codecs, I expect that previous one which we were using(SND_SOC_RT5682) is not a wrong flag and I expect to use
SND_SOC_RT5682 as it is still available.

Thanks,
Vishnu

Right, and I can't understand the commit message at all.  What's the actual issue here and how could this fix it - in what situation wouldn't you need one of the bus modules?
