The snprintf calls filling cht_rt5645_cpu_dai_name / cht_rt5645_codec_aif_name
always fill them with the same string ("ssp0-port" resp "rt5645-aif2") so
instead of keeping these buffers around and making the cpu_dai_name /
codec_aif_name point to this, simply update the foo_dai_name and foo_aif_name pointers to
directly point to a string constant containing the desired string.

Need Nariman's Signoff-of-by tag here.

Yes, Nariman can you resend with your S-o-b added once the other part
of this discussion is resolved?

Note you need to pass

--subject-prefix="PATCH v2"

To git send-email when sending out the new version with your S-o-b added
to the 3 patches which you are not the author of.

same, not equivalent. SSP2_AIF2 is not handled.

Same remark from me, and also the same for the 3th patch you've
responded to.

and same here, SSP0_AIF1 will no longer work.

      /* override plaform name, if required */
      platform_name = mach->mach_params.platform;
