For the record, I would prefer if we went with Florian's first
recommendation per the following message:

  - https://lore.kernel.org/linux-pci/159c5fcf-709d-42ba-8d45-a70b109fe261@broadcom.com

To clearly separate errors returned from the value being updated.

Albeit, this is fine too, especially as Jim expressed no opinion either
way regarding his preference.
