How do you think about a wording variant like the following?

   Subject:
   [PATCH v2] nfp: abm: Fix incomplete release of system resources in nfp_abm_vnic_set_mac()

   Change description:
   …
   Thus add a call of the function “nfp_nsp_close” for the completion
   of the exception handling.

I suggest to reconsider the order for resource clean-up function calls
a bit more.

+		nfp_nsp_close(nsp);
-		eth_hw_addr_random(nn->dp.netdev);
-		return;
+		goto generate_random_address;


Should such a jump target be added in another update step?

Would you like to add the tag “Fixes”?
