ASoC: qcom: Return an error for invalid PCM trigger command
Fix a compile warning sound/soc/qcom/lpass-cpu.c: In function ‘lpass_cpu_daiops_trigger’: sound/soc/qcom/lpass-cpu.c:224:2: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized] return ret; ^ Although switch () lists the most of existing cases, it's still better to cover the rest as an error properly.
