Hello Greg,

During Syzkaller reproducer testing on 5.4.y (5.4.118-rc1) the following crash occurred:

BUG: KASAN: use-after-free in hci_send_acl https://syzkaller.appspot.com/bug?extid=98228e7407314d2d4ba2

We cherry-pick'd upstream commit 5c4c8c95 to 5.4.y and the crash no longer occurs (rebooted 10 times with the fix commit - no failures). https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...

Now queued up, thnaks.
