ASoC: component: suppress uninitialized-variable warning
Old versions of gcc (tested on gcc-4.8) produce a warning for
correct code:
sound/soc/soc-compress.c: In function 'soc_compr_open':
sound/soc/soc-compress.c:75:28: error: 'component' is used uninitialized in this function [-Werror=uninitialized]
struct snd_soc_component *component, *save = NULL;
Change the for_each_rtd_components() macro to ensure 'component'
gets initialized to a value the compiler does not complain about.
