[PATCH v2] ASoC: soc-compress: avoid false-positive Wuninitialized warning

From: Rong Chen
Date: Thu Apr 23 2020 - 20:54:59 EST


gcc-6.5 and earlier show a new warning:

sound/soc/soc-compress.c: In function âsoc_compr_openâ:
sound/soc/soc-compress.c:75:28: warning: âcomponentâ is used uninitialized in this function [-Wuninitialized]
struct snd_soc_component *component, *save = NULL;
^~~~~~~~~

Simplest fix is to initialize it to avoid the warning.
