This change is completely unrelated and probably doesn't make much sense.

There does seems to have 2 watches for the exact same thing.

You probably don't need the dev->watch anymore.

This patch is packing a lot of changes perhaps you should consider splitting.

I guess if you want to be consist you should name the var session here as well.

Subject: [PATCH_v6 4/5] bnep: Refactored bnep connect and disconnect calls

Refactored bnep connect and disconnect calls to simplify and
keeping bnep related functionality behind curtains.
Provided bnep struct globally. bnep_connect calls takes
care of bnep_setup until interface up then connect callback
will be called. Provided bnep_set_disconnect. Set disconnect
when connect call succeeds. bnep_disconnect should be
called only when iface is up/connected.
