Lv Yunlong 0c2bc14891 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.
