However keeping the explicit .driver_data = 0 to have a contrast to
other `pci_device_id`s having a non-zero .driver_data in the same driver
is also a good reason to keep the (technically redundant) assignment.
For other drivers I dropped these assignments if this is possible for
all array members.

Having said that I don't intend to rework the patch for this suggestion.
