Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth
Johan Hedberg says:
====================
pull request: bluetooth 2014-12-17
Here's the first direct (i.e. skipping the wireless tree) bluetooth pull
request for you, intended for 3.19. It's just one patch: a fix from
Marcel for for remote service discovery filtering which also fixes a
'used uninitialized' compiler warning.
Please let me know if there are any issues pulling. Thanks.
