Hi all,

After merging the bluetooth tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from net/bluetooth/mgmt.c:30:
net/bluetooth/mgmt.c: In function 'load_link_keys':

cc1: all warnings being treated as errors

Caused by commit

  c858dc985d70 ("Bluetooth: MGMT: Ignore keys being loaded with invalid type")

I have used the bluetooth tree from next-20230829 for today.
