I'm not sure about the places where you set the value to NULL, but the
place in close_cfm which you remove isn't acceptable as such. It was
originally created to fix the issue reported in this thread:
http://marc.info/?l=linux-bluetooth&m=129190286303247&w=2

Only a fix which doesn't break the use-case reported there can be
accepted upstream. FWIW, the commit that introduced the fix is de96fcd8.
