[PATCH 2.6] hw_random.c: replace pci_find_device

[PATCH 2.6] hw_random.c: replace pci_find_device

[Hanna Linder]

As pci_find_device is going away I've replaced it with pci_get_device.
for_each_pci_dev is a macro wrapper around pci_get_device.
If someone with this hardware could test it I would appreciate it.

Thanks.

I just pulled from Linus bk, for_each_pci_dev isn't defined anywhere.
I get compile errors in hw_random.c.

[jonsmirl@smirl linux-2.5]$ grep -rI for_each_pci_dev *
drivers/char/hw_random.c:       for_each_pci_dev(pdev) {
SCCS/s.ChangeSet:\x01c for_each_pci_dev is a macro wrapper around pci_get_device.

Woops, looks like this broke the build, I don't have for_each_pci_dev
anywhere in my tree but one use in hw_random.c and one comment in
SCCS/s.ChangeSet.

thanks,

I believe some people missed Hanna's first patch which defined
for_each_pci_dev so she sent it again a few days after. Here is her
message again...

I wrote this macro last week and was recently asked to resend it in case people
missed the original submission. I have been using it during my conversion to
pci_get_device and it seems to be fine.
