gcc-6.5 and earlier show a new warning:
sound/soc/soc-compress.c: In function ‘soc_compr_open’: sound/soc/soc-compress.c:75:28: warning: ‘component’ is used uninitialized in this function [-Wuninitialized] struct snd_soc_component *component, *save = NULL; ^~~~~~~~~
Simplest fix is to initialize it to avoid the warning.
