From 667ebc97c99a2ea9279bf3fdd791d97adfafbbc2 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 10 Oct 2017 11:20:10 +0200 Subject: [PATCH] ASoC: dapm: add initialization for w_param_text pointer We now allocate the array conditionally, but we always pass the pointer to the new snd_soc_dapm_free_kcontrol() function, which introduces a warning for the case that it is not initialized: sound/soc/soc-dapm.c: In function 'snd_soc_dapm_new_pcm': sound/soc/soc-dapm.c:3940:2: error: 'w_param_text' may be used uninitialized in this function [-Werror=maybe-uninitialized] As snd_soc_dapm_free_kcontrol() is global, it doesn't get inlined and gcc fails to notice that we don't actually access the array in that case, so the code is actually safe. Adding an initialization for the array pointer shuts up the warning.
