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:
â
Thus add a call of the function ânfp_nsp_closeâ 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 âFixesâ?
