Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next
Johan Hedberg says:
====================
pull request: bluetooth-next 2016-07-19
Here's likely the last bluetooth-next pull request for the 4.8 kernel:
- Fix for L2CAP setsockopt
- Fix for is_suspending flag handling in btmrvl driver
- Addition of Bluetooth HW & FW info fields to debugfs
- Fix to use int instead of char for callback status.
The last one (from Geert Uytterhoeven) is actually not purely a
Bluetooth (or 802.15.4) patch, but it was agreed with other maintainers
that we take it through the bluetooth-next tree.
Please let me know if there are any issues pulling. Thanks.
