Title
Bluetooth: ISO: Fix multiple init when debugfs is disabled
Summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Fix multiple init when debugfs is disabled If bt_debugfs is not created successfully, which happens if either CONFIG_DEBUG_FS or CONFIG_DEBUG_FS_ALLOW_ALL is unset, then iso_init() returns early and does not set iso_inited to true. This means that a subsequent call to iso_init() will result in duplicate calls to proto_register(), bt_sock_register(), etc. With CONFIG_LIST_HARDENED and CONFIG_BUG_ON_DATA_CORRUPTION enabled, the duplicate call to proto_register() triggers this BUG(): list_add double add: new=ffffffffc0b280d0, prev=ffffffffbab56250, next=ffffffffc0b280d0. ------------[ cut here ]------------ kernel BUG at lib/list_debug.c:35!

This change removes the early return. The check for iso_debugfs being NULL was unnecessary, it is always NULL when iso_inited is false.
