====================
pull request: bluetooth 2015-07-02

A couple of regressions crept in because of a patch to use proper list
APIs rather than manually reading & writing the next/prev pointers
(commit 835a6a2f). Turns out this was
masking a few bugs: a missing INIT_LIST_HEAD() call and incorrectly
using list_del() rather than list_del_init(). The two patches in this
set fix these, and it'd be nice they could still make it to 4.2-rc1 to
avoid new bug reports from users.

Please let me know if there are any issues pulling. Thanks.
