As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() and pci_enable_msix_range()
interfaces.

Networking code formats multi-line comments slightly differently to the rest of the kernel:

/* bla
 * bla
 */

Although, you're only moving what was there before you, maybe it's a good time to get this right.
