[PATCH] arch/ppc: Remove an unnecessary pci_dev_put.

From: Julia Lawall
Date: Sat Nov 03 2007 - 11:15:24 EST


From: Julia Lawall <julia@xxxxxxx>

Remove an unnecessary pci_dev_put. pci_dev_put is called implicitly by the
subsequent call to pci_get_device.

The problem was detected using the following semantic patch, and corrected
by hand.

expression dev;
expression E;

- pci_dev_put(dev)
... when != dev = E
- pci_get_device(...,dev)
