Hi all,

Today's linux-next merge of the bluetooth tree got a conflict in:

  include/net/bluetooth/hci_core.h

between commit:

  af24e338bf5da ("Bluetooth: ISO: fix race of kfree vs kref_get_unless_zero")

from the origin tree and commit:

  d740cf77461a4 ("Bluetooth: add annotations for l2cap_data locking context")

from the bluetooth tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
