Sorry, didn't get to reply to your comment in time. This can only be a
mis-match between crash and debug. And the 'name' field is just a string
version of the array index enum. So I would have just gone with "Unit
mismatch for crash and debug sections: %d vs %d".

Missed this in the previous patch set but this is a weird warning! Why
have fixed strings printed via %s?! Seems like it would be better to have:
guc_warn(guc, "Log verbosity param out of range: %d vs %d",
i915->params.guc_log_level, GUC_LOG_LEVEL_MAX);
