Thanks, and apologies if I still have this mixed up.
I'm wondering if the following commit message would make things clearer.

Subject: [PATCH net-next v3 2/4] hinic3: remove defensive txq_num check

Since commit 1f3838b84a63 ("hinic3: Add Rss function") nic_dev->num_txqs
cannot be zero in hinic3_alloc_txqs(). So remove the check for this case.
