ASoC: soc-pcm: don't use bit-OR'ed error
Current soc-pcm is using bit-OR'ed error ret |= snd_soc_component_close(component, substream); ret |= snd_soc_component_hw_free(component, substream); The driver may return arbitrary error codes so they can conflict. The bit-OR'ed error works only if the return code is always consistent. This patch fixup it, and use *last* ret value.
