From: Likun Gao <Likun.Gao@xxxxxxx> Some asic may not support for some message of set mp1 state. If the return value of smu_send_smc_msg is -EINVAL, that means it failed to send msg to smc as it can not map an valid message for the ASIC. And with that case, smu_set_mp1_state should be skipped as those ASIC was in fact do not support for that.
