[PATCH 0/3] ASoC: remove SND_SOC_BYTES_EXT

[PATCH 0/3] ASoC: remove SND_SOC_BYTES_EXT

[Vinod Koul]

The SND_SOC_BYTES_TLV and SND_SOC_BYTES_EXT provide similar functionality,
with only difference that SND_SOC_BYTES_EXT have limitations of 512 bytes
as parameters whereas no such restrictions on SND_SOC_BYTES_TLV

So remove SND_SOC_BYTES_EXT and update users to use SND_SOC_BYTES_TLV

Hmm, won't this break user-space?  Both use the difference access
methods, so I wonder how they can be kept compatible.

Yes they will, so should we then keep these and mark SND_SOC_BYTES_EXT
depricated ..?

Mark what should we do with these

Re: [PATCH 1/3] ASoC: Intel: Hsw: Move driver to use SND_SOC_BYTES_TLV

[Han Lu]

There was no special reason for me to use SND_SOC_BYTES_EXT here. But 
will this patch
influences user space, since the parameter list of hsw_waves_param_get() 
be modified?

Han Lu

Looks good to me, I think the TLV byte control stuff has been
merged in tinyalsa now so no problems there.
