PCI: Hotplug: Fix leaks in IBM Hot Plug Controller Driver - ibmphp_init_devno()
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.
Please consider applying.
