commit c66150824b8a ("ASoC: dapm: add code to configure dai link parameters") introduced the following build warning:
sound/soc/soc-dapm.c: In function 'snd_soc_dapm_new_pcm': sound/soc/soc-dapm.c:3389:4: warning: passing argument 1 of 'snprintf' discards 'const' qualifier from pointer target type snprintf(w_param_text[count], len,
This patch fixes this by switching to using devm_kasprintf. This also saves a couple of lines of code.

Changes since v2: - Use devm_kasprintf
