Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next

Johan Hedberg says:

====================
pull request: bluetooth-next 2015-04-04

Here's what's probably the last bluetooth-next pull request for 4.1:

 - Fixes for LE advertising data & advertising parameters
 - Fix for race condition with HCI_RESET flag
 - New BNEPGETSUPPFEAT ioctl, needed for certification
 - New HCI request callback type to get the resulting skb
 - Cleanups to use BIT() macro wherever possible
 - Consolidate Broadcom device entries in the btusb HCI driver
 - Check for valid flags in CMTP, HIDP & BNEP
 - Disallow local privacy & OOB data combo to prevent a potential race
 - Expose SMP & ECDH selftest results through debugfs
 - Expose current Device ID info through debugfs

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