Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
Please pull this batch of updates intended for the 3.17 stream...
This is primarily a Bluetooth pull. Gustavo says:
"A lot of patches to 3.17. The bulk of changes here are for LE support.
The 6loWPAN over Bluetooth now has it own module, we also have support for
background auto-connection and passive scanning, Bluetooth device address
provisioning, support for reading Bluetooth clock values and LE connection
parameters plus many many fixes."
The balance is just a pull of the wireless.git tree, to avoid some
pending merge problems.
