Subject: [PATCH] net: use pci_dev->revision, again
Several more network drivers that read the device's revision ID
from the PCI configuration register were merged after the commit
44c10138fd4bbc4b6d6bff0873c24902f2a9da65 (PCI: Change all drivers
to use pci_device->revision), so it's time to do another pass of
conversion to using the 'revision' field of 'struct pci_dev'...
Signed-off-by: Sergei Shtylyov <sshtylyov@...mvista.com>

The patch is against the recent Linus' tree.
