up. To maintain netdev->dev_addr in this tree we need to make all

prevent_wake logic is backward since what it is really checking is
if the device may wakeup the system or not, not that it will prevent
the to be awaken.
Also looking on how other subsystems have the entry as power/wakeup
this also renames the force_prevent_wake to force_wakeup in vhci driver.

This moves code from hci_suspend_notifier to hci_{suspend,resume}_dev
since some driver may handle pm directly using
HCI_QUIRK_NO_SUSPEND_NOTIFIER they would instead call
hci_{suspend,resume}_dev directly and we want that to have the same
behavior regardless of where pm is being handled.

The existence of the experimental feature identifiy is the indication
that it is supported or not. No extra flag needed and the initial flag
should define if a feature is enabled or not. This is actually defined
in the management API definition.

During system suspend, advertisement monitoring is disabled by setting
the HCI_VS_MSFT_LE_Set_Advertisement_Filter_Enable to False. This
disables the monitoring during suspend, however, if the controller is
monitoring a device, it sends HCI_VS_MSFT_LE_Monitor_Device_Event to
indicate that the monitoring has been stopped for that particular
device. This event may occur after suspend depending on the
low_threshold_timeout and peer device advertisement frequency, which
causes early wake up.
Right way to disable the monitoring for suspend is by removing all the
monitors before suspend and re-monitor after resume to ensure no events
are received during suspend. This patch fixes this suspend/resume issue.
Following tests are performed:
- Add monitors before suspend and make sure DeviceFound gets triggered
- Suspend the system and verify that all monitors are removed by kernel
but not Released by bluetoothd
- Wake up and verify that all monitors are added again and DeviceFound
gets triggered

Passing NULL to PTR_ERR will result in 0 (success), also since the likes of
bt_skb_sendmsg does never return NULL it is safe to replace the instances of

This splits the msft_do_{open/close} to msft_do_{open/close} and
msft_{register/unregister}. With this change it is possible to retain
the MSFT extension info irrespective of controller power on/off state.
This helps bluetoothd to report correct 'supported features' of the
controller to the D-Bus clients event if the controller is off. It also
re-reads the MSFT info upon every msft_do_open().
The following test steps were performed.
1. Boot the test device and verify the MSFT support debug log in syslog.
2. Power off the controller and read the 'supported features', power on
and read again.
3. Restart the bluetoothd and verify the 'supported features' value.
