Subject: [PATCH] ASoC: Intel: bytcr_rt5651.c: remove string buffers 'byt_rt5651_cpu_dai_name' and 'byt_rt5651_cpu_dai_name'

From: Jordy Ubink <jordyubink@...mail.nl>

The snprintf calls filling byt_rt5651_cpu_dai_name / byt_rt5651_cpu_dai_name always fill them with the same string (ssp0-port" resp "rt5651-aif2"). So instead of keeping these buffers around and making the cpu_dai_name / codec_dai_name point to this, simply update the foo_dai_name pointers to directly point to a string constant containing the desired string.
