Hi Evan,
The error prompts in function smu_cmn_send_smc_msg_with_param do not cover all failed cases since it only prints reg stat SMU_RESP_NONE,
SMU_RESP_BUSY_OTHER or response -EREMOTEIO. I think it is better update reg error stat judgment conditions to print more error msg.
Regards,
Stanley

Hi Stanley,
There is already error prompts in the smu_cmn_send_smc_msg_with_param() used by the API mentioned below.
Can that cover your use case?
