[alsa-devel] [PATCH 3/4] ASoC: Intel: bytcr_rt5651: Remove unnecessary string buffers and snprintf calls

[Hans de Goede]

From: Jordy Ubink <jordyubink at hotmail.nl>

The snprintf calls filling byt_rt56*_codec_aif_name/byt_rt56*_cpu_dai_name
always fill them with the same string ("rt56*-aif2" resp. ssp0-port").
So instead of keeping these buffers around and making codecs->dai_name /
cpus->dai_name point to them, simply update the *->dai_name pointers to
directly point to a string constant containing the desired string.
