Reviewed-by: Hawking Zhang <Hawking.Zhang at amd.com>

Per discussion, please have a separated patch to replace all the "DRM_INFO" with "dev_info" in per IP query_ras_error_count callback function so that we will have clear picture on which errors are from which nodes when harvest all the RAS errors in one gpu recovery worker.

Regards,
Hawking
