ipack/carriers/tpci200: Fix a double free in tpci200_pci_probe
commit 9272e5d0028d45a3b45b58c9255e6e0df53f7ad9 upstream.
In the out_err_bus_register error branch of tpci200_pci_probe,
tpci200->info->cfg_regs is freed by tpci200_uninstall()->
tpci200_unregister()->pci_iounmap(..,tpci200->info->cfg_regs)
in the first time.
But later, iounmap() is called to free tpci200->info->cfg_regs
again.
My patch sets tpci200->info->cfg_regs to NULL after tpci200_uninstall()
to avoid the double free.
Fixes: cea2f7cdff2af ("Staging: ipack/bridges/tpci200: Use the TPCI200 in big endian mode")
