A function with unused automatic variables was recently introduced to this library, then compiler generates below warnings. pcm.c: In function ‘build_link’: pcm.c:213:6: warning: unused variable ‘i’ [-Wunused-variable] int i, num_hw_configs = 0, err = 0; ^ pcm.c:210:43: warning: unused variable ‘cmpnt’ [-Wunused-variable] struct snd_soc_tplg_link_cmpnt *codec, *cmpnt; ^~~~~ pcm.c:210:35: warning: unused variable ‘codec’ [-Wunused-variable] struct snd_soc_tplg_link_cmpnt *codec, *cmpnt; ^~~~~ pcm.c:209:20: warning: unused variable ‘ref_elem’ [-Wunused-variable] struct tplg_elem *ref_elem = NULL; This commit removes them.
