+       dev_info(adev->dev,
+               "MCA_UMC_STATUS(0x%llx): Val:%llu, Poison:%llu, Deferred:%llu, PCC:%llu, UC:%llu, TCC:%llu\n",
+               mc_umc_status,

Please also print out socket id for UMC MCA status.

+       dev_info(smu->adev->dev, "MSG %s(%d) query %s MCA count result:%u\n",
+               (msg == SMU_MSG_QueryValidMcaCeCount) ?
+                       "SMU_MSG_QueryValidMcaCeCount" : "SMU_MSG_QueryValidMcaCount",
+               msg,
+               (msg == SMU_MSG_QueryValidMcaCeCount) ? "CE" : "UE",
+               *count);
+

This seems redundant or was added for debugging purpose. We can drop this print since there is log to cover failures.

Regards,
Hawking
