You mean v3? Make sure to include a changelog, if possible. A small nitpick: the PCI_DEVICE_DATA() is technically a macro rather than a function, so you could update both the subject line and the commit message accordingly, if you want. Also, since you are about to send another version, add period at the end of the sentence in the commit message. Aside of the above, it's a nice refactor, thank you! Krzysztof
