Subject: [PATCH] ASoC: Intel: cht_bsw_rt5645: Remove unnecessary string buffers and snprintf calls
Git-commit: 791a0059e2585c094c2b8ff61983074c657dabf8
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518

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 cpus->dai_name / codecs->dai_name point to this,
simply update the *->dai_name pointers to directly point to a string
constant containing the desired string.
