[ Upstream commit 7f1186a8d738661b941b298fd6d1d5725ed71428 ]
snd_soc_dai_set_tdm_slot() calls .xlate_tdm_slot_mask() or snd_soc_xlate_tdm_slot_mask(), but didn't check its return value. Let's check it.
This patch might break existing driver. In such case, let's makes each func to void instead of int.
