From 46172b6c26667133b9945b916b6223cc87bbf10c Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Wed, 25 Mar 2015 11:22:35 +0000 Subject: ASoC: dapm: Fix build warning 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.
