Wang Hai d2e7a4d20f Bluetooth: cmtp: fix possible panic when cmtp_init_sockets() fails ... [ Upstream commit 2a7ca7459d ] I got a kernel BUG report when doing fault injection test: ------------[ cut here ]------------ kernel BUG at lib/list_debug.c:45! ... RIP: 0010:__list_del_entry_valid.cold+0x12/0x4d ... Call Trace: proto_unregister+0x83/0x220 cmtp_cleanup_sockets+0x37/0x40 [cmtp] cmtp_exit+0xe/0x1f [cmtp] do_syscall_64+0x35/0xb0 entry_SYSCALL_64_after_hwframe+0x44/0xae If cmtp_init_sockets() in cmtp_init() fails, cmtp_init() still returns success. This will cause a kernel bug when accessing uncreated ctmp related data when the module exits.
