Hi

thanks for improving the driver.

priv->msi_enabled is unused by the driver. Better remove it entirely. If
the MSI flag will be required later, there's already struct
pci_dev.msi_enabled.

Apart from that, the one-by-one approach to patching is somewhat
tedious. Could you collect patches and send them out in batches? It
would make reviewing easier and give reviewers an idea of where you're
going with the driver.

Best regards
Thomas
