The qmi_wwan merge was trivial.
The caif_hsi.c, on the other hand, was not. It's a conflict between

device with ops structure.") in the net-next tree and commit
39abbaef19cd0a30be93794aa4773c779c3eb1f3 ("caif-hsi: Postpone init of
HIS until open()") in the net tree.
I did my best with that one and will ask Sjur to check it out.

The generic HID driver is obviously not a special driver, so move it
outside of the special drivers menu. Explain the usage and make the
default follow the HID setting. This should simplify migration from
older kernels. While at it, remove the redundant HID_SUPPORT option
and modify the HID and USB_HID entries to better explain the bus
structure.

Devices that do not have a special driver are handled by the generic
driver. This patch does the same thing using device groups; Instead of
forcing a particular driver, the appropriate driver is picked up by
udev. As a consequence, one can now move a device from generic to
specific handling by a simple rebind. By adding a new device id to the
generic driver, the same thing can be done in reverse.

Calling module_put(THIS_MODULE) is *never* safe when we cannot go sure that we
own at least two references. This is because the call may unload our module
before it returns and then the "return" will jump into invalid memory.
Gladly, module.h provides a wrapper for kthread-users: module_put_and_exit().
This puts our module and then exits the kthread without returning to the module.
This patch fixes the hidp kthread to use this wrapper instead of manually
freeing its own reference. See nfsd or lockd for other kthreads using this.
Calling __module_get() inside the kthread is safe as the hidp module will always
wait until the kthread sets "waiting_for_startup" to 0.

Current hidp driver purges the in/out queue on HID shutdown, but does
not prevent further I/O. If a driver uses hidp_output_raw_report or
hidp_get_raw_report during shutdown, the driver hangs for 5 or 10
seconds per call until it gets a timeout.
That is, if the output queue of an HID driver has 10 messages pending,
it will take 50s until hid_destroy_device() will return. The
hidp_session_sem semaphore is held during shutdown so no other HID
device may be added/removed during this time.
This patch makes hidp_output_raw_report and hidp_get_raw_report fail if
session->terminate is true. Also hidp_session will wakeup all current
calls to these functions to cancel the current operations.
We already purge the current I/O queues on hidp_stop(), so this data loss
does not change the behaviour of the HID drivers.

Partial revert of commit aabf6f89. When the hidp session thread
was converted from kernel_thread to kthread, the atomic/wakeups
were replaced with kthread_stop. kthread_stop has blocking semantics
which are inappropriate for the hidp session kthread. In addition,
the kthread signals itself to terminate in hidp_process_hid_control()
- it cannot do this with kthread_stop().
Lastly, a wakeup can be lost if the wakeup happens between checking
for the loop exit condition and setting the current state to
TASK_INTERRUPTIBLE. (Without appropriate synchronization mechanisms,
the task state should not be changed between the condition test and
the yield - via schedule() - as this creates a race between the
wakeup and resetting the state back to interruptible.)

The current implementation of hidp_output_raw_report() relies only on
the Control channel even for Output reports, and the BT HID
specification [1] does not mention using the DATA message for Output
reports on the Control channel (see section 7.9.1 and also Figure 11:
SET_ Flow Chart), so let us just use SET_REPORT.
This also fixes sending Output reports to some devices (like Sony
Sixaxis) which are not able to handle DATA messages on the Control
channel.
Ideally hidp_output_raw_report() could be improved to use this scheme:
Feature Report -- SET_REPORT on the Control channel
Output Report -- DATA on the Interrupt channel
for more efficiency, but as said above, right now only the Control
channel is used.

Move the call to hid_add_device() (which calls a device's probe() function)
to after the kernel_thread() call which starts the hidp_session() thread.
This ensures the Bluetooth receive socket is fully running by the time a
device's probe() function is called. This way, a device can communicate
(send and receive) with the Bluetooth device from its probe() function.
