[PATCH 1/4] Bluetooth: Remove bogus inline declaration from l2cap_chan_connect

[johan.hedberg]

From: Johan Hedberg <johan.hedberg@intel.com>

As reported by Dan Carpenter this function causes a Sparse warning and
shouldn't be declared inline:

include/net/bluetooth/l2cap.h:837:30 error: marked inline, but without a
definition"

[PATCH 2/4] Bluetooth: Move mgmt related flags from hdev->flags to hdev->dev_flags

[johan.hedberg]

From: Johan Hedberg <johan.hedberg@intel.com>

There's no point in exposing these to user-space (which is what happens
to everything in hdev->flags) so move them to dev_flags instead.

[johan.hedberg]

From: Johan Hedberg <johan.hedberg@intel.com>

The HCI_MGMT flag should not be cleared when resetting a HCI device.

[PATCH 4/4] Bluetooth: Sort to-be-resolved devices by RSSI during discovery

[johan.hedberg]

From: Johan Hedberg <johan.hedberg@intel.com>

This patch makes sure that devices with stronger signal (RSSI closer to
0) are sorted first in the resolve list and will therefore get their
names resolved first during device discovery. Since it's more likely
that the device the user is trying to discover has a strong signal due
to its proximity this ensures that the user gets the "device found"
event for it more quickly.
