There is something odd going on with patch here. Notice how it says
hns3_nic_set_features(). This is not the function being patched, it is
actually the next one, hns3_nic_get_stats64(), which makes a lot more
sense.

Is it because the static void is on the previous line?

It would be nice if the function was correctly reported. It makes it
easier to review the patch.
