Summary
Bluetooth: Fix not cleanup led when bt_init fails
Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: Fix not cleanup led when bt_init fails

btinit() calls btledsinit() to register led, but if it fails later, btleds_cleanup() is not called to unregister it.

This can cause panic if the argument "bluetooth-power" in text is freed and then another ledtriggerregister() tries to access it:
