There was a lockdep which led to commit
fad003b6c8e3d ("Bluetooth: Fix inconsistent lock state with RFCOMM")
Lockdep noticed that `sk->sk_lock.slock' was acquired without disabling
the softirq while the lock was also used in softirq context.
Unfortunately the solution back then was to disable interrupts before
acquiring the lock which however made lockdep happy.
It would have been enough to simply disable the softirq. Disabling
interrupts before acquiring a spinlock_t is not allowed on PREEMPT_RT
because these locks are converted to 'sleeping' spinlocks.
Use spin_lock_bh() in order to acquire the `sk_lock.slock'.

Bluetooth PTS test case HFP/AG/ACC/BI-12-I accepts SCO connection
with invalid parameter at the first SCO request expecting AG to
attempt another SCO request with the use of "safe settings" for

- Add device tree bindings for Qualcomm QCA9377 device
- Add support for experimental features configuration through mgmt
- Add driver hook to prevent wake from suspend
- Add support for waiting for L2CAP disconnection response
- Multiple fixes & cleanups to the btbcm driver
- Add support for LE scatternet topology for selected devices
- A few other smaller fixes & cleanups
Please let me know if there are any issues pulling. Thanks.

Whenever we disconnect a L2CAP connection, we would immediately
report a disconnection event (EPOLLHUP) to the upper layer, without
waiting for the response of the other device.
This patch offers an option to wait until we receive a disconnection
response before reporting disconnection event, by using the "how"
parameter in l2cap_sock_shutdown(). Therefore, upper layer can opt
to wait for disconnection response by shutdown(sock, SHUT_WR).
This can be used to enforce proper disconnection order in HID,
where the disconnection of the interrupt channel must be complete
before attempting to disconnect the control channel.

After sending Inquiry Cancel command to the controller, it is possible
that Inquiry Complete event comes before Inquiry Cancel command complete
event. In this case the Inquiry Cancel command will have status of
Command Disallowed since there is no Inquiry session to be cancelled.
This case should not be treated as error, otherwise we can reach an
inconsistent state.
Example of a btmon trace when this happened:
< HCI Command: Inquiry Cancel (0x01|0x0002) plen 0
> HCI Event: Inquiry Complete (0x01) plen 1
Status: Success (0x00)

Let drivers have a hook to disable configuring scanning during suspend.
Drivers should use the device_may_wakeup function call to determine
whether hci should be configured for wakeup.
For example, an implementation for btusb may look like the following:
bool btusb_prevent_wake(struct hci_dev *hdev)
{
struct btusb_data *data = hci_get_drvdata(hdev);
return !device_may_wakeup(&data->udev->dev);
}

When a device is suspended, it doesn't need to be as responsive to
connection events. Increase the interval to 640ms (creating a duty cycle
of roughly 1.75%) so that passive scanning uses much less power (vs
previous duty cycle of 18.75%). The new window + interval combination
has been tested to work with HID devices (which are currently the only
devices capable of wake up).

Currently the MITM flag is only unset when the io capability is set

When scheduling TX packets, send all SCO/eSCO packets first, check for
pending SCO/eSCO packets after every ACL/LE packet and send them if any
are pending. This is done to make sure that we can meet SCO deadlines
on slow interfaces like UART.
If we were to queue up multiple ACL packets without checking for a SCO
packet, we might miss the SCO timing. For example:
The time it takes to send a maximum size ACL packet (1024 bytes):
t = 10/8 * 1024 bytes * 8 bits/byte * 1 packet / baudrate
where 10/8 is uart overhead due to start/stop bits per byte
Replace t = 3.75ms (SCO deadline), which gives us a baudrate of 2730666.
At a baudrate of 3000000, if we didn't check for SCO packets within 1024
bytes, we would miss the 3.75ms timing window.

When handling auto-connected devices, we should execute the rest of the
connection complete when it was previously discovered and it is an ACL
connection.

If Bluetooth fails to enter the suspended state correctly, restore the
state to running (re-enabling scans). PM_POST_SUSPEND is only sent to
notifiers that successfully return from PM_PREPARE_SUSPEND notification
so we should recover gracefully if it fails.

BlueZ cancels adv when starting a scan, but does not cancel a scan when
starting to adv. Neither is required, so this brings both to a
consistent state (of not affecting each other). Some very rare (I've
never seen one) BT 4.0 chips will fail to do both at once. Even this is
ok since the command that will fail will be the second one, and thus the
common sense logic of first-come-first-served is preserved for BLE
requests.

Smatch complains about the indenting:
net/bluetooth/l2cap_sock.c:1027 l2cap_sock_recvmsg()
warn: inconsistent indenting
It looks like this is supposed to be an "else if" condition.
