reply [PATCH v2] ASoC: sdw_utils: senary: handle a missing name_prefix

[<qianghua.wang@senarytech.com>]

Hi Bard,
	Thanks for the review. I agree the right fix is to ensure
name_prefix is set via codec_conf / component probe, not to paper over NULL
in sdw_utils.
The v2 follow-up was based on debug logs and instrumentation from jfdnet, a
community contributor on GitHub issue #6012. We have not reproduced this on
SN6245 hardware ourselves yet (SN6244 only in our lab).
Please hold off on reviewing or merging
[PATCH v2] ASoC: sdw_utils: senary: handle a missing name_prefix until we
have the same hardware and can test and align the fix locally. 
I will follow up after that.
Thanks,
Qianghua Wang

In what case will codec_conf not apply the prefix?
Won't it be better to ensure that the name_prefix is always set?
