Merge branch 'for-upstream' of... 

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



Johan Hedberg says:

====================
pull request: bluetooth-next 2015-03-19

This wont the last 4.1 bluetooth-next pull request, but we've piled up
enough patches in less than a week that I wanted to save you from a
single huge "last-minute" pull somewhere closer to the merge window.

The main changes are:

 - Simultaneous LE & BR/EDR discovery support for HW that can do it
 - Complete LE OOB pairing support
 - More fine-grained mgmt-command access control (normal user can now do
   harmless read-only operations).
 - Added RF power amplifier support in cc2520 ieee802154 driver
 - Some cleanups/fixes in ieee802154 code

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