I think so too, but some drivers, that uses pci_find_device are broken 
for a long time and nobody uses it at all.

So what should I do? I want others not to use pci_find_device 
furthermore, so I sent patch that marks it deprecated. Greg sent, that 
he wants to remove them and wants to kill 'em all from the tree. When I 
rewrote the 2 drivers, nobody wanted to test them and nobody acked them, 
nobody did anything. So:
a) rewrite non-broken drivers, the rest kill (or not to kill, only mark 
find as deprecated and let them live for some next time)
b) rewrite all
c) change find to get + dev_put
d) others: ................
[What about oss drivers?]

So, Greg and Jeff, your opinions?

thanks,
