Subject: pci-hotplug: fix leaks in IBM Hot Plug Controller Driver - ibmphp_init_devno()
From: Jesper Juhl <jesper.juhl@xxxxxxxxx>
In drivers/pci/hotplug/ibmphp_core.c::ibmphp_init_devno() we allocate space
dynamically for a PCI irq routing table by calling
pcibios_get_irq_routing_table(), but we never free the allocated space.
This patch frees the allocated space at the function exit points.
Spotted by the Coverity checker. Compile tested only.
