Subject: HID: ignore Jabra speakerphones HID interface

Add a quirk to ignore Jabra speakerphone 410 and 510 devices HID
interface.
On those devices, the USB audio interface is working nicely,
but the HID interface is not working with the kernel usbhid driver,
and it requires a specific userspace program.
We could unbind it from userspace but just attaching the usbhid driver has
sometimes nasty effects:
either confusing the device state machine or triggering a storm of volume key
events making eventual sound UI blinking like crazy.

Subject: HID: driver for PS2/3 Buzz controllers

This patch adds support for PS2/3 Buzz controllers into hid-sony

It has been tested on Debian 7 with kernel version 3.10.0-rc2. Unfortunately
I can't test the patch with a regular six-axis controller myself.

Subject: HID: sony: fix leds dependency

The newly added support for Buzz controller

- introduced Kconfig selection of LEDS_CLASS
- introduced conditional preprocessor checking for CONFIG_LEDS_CLASS

This has multiple problems -- namely select doesn't work transitively,
so it shouldn't be used. On the other hand the code assumed that LEDS_CLASS
is enabled in some places, but not everywhere.

Put LEDS_CLASS as a Kconfig dependency for hid-sony and remove all the
CONFIG_LEDS_CLASS conditionals from hid-sony.

Subject: HID: Add support for Holtek gaming mouse 04d9:a04a
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This mouse is sold as Tracer Sniper TRM-503, NOVA Gaming Slider X200 and
Zalman ZM-GM1, and reports too high usage maximum and logical maximum
(like 04d9:a067, but its report descriptor is different). This patch
adds its USB ID and fixes the report descriptor in the same way.

Note: I don't actually have such a mouse to test, I took the report
descriptor posted at https://bugzilla.novell.com/show_bug.cgi?id=774676,
compared it to the one from 04d9:a067 and changed the offsets
accordingly (all numbers minus 9, since it is 9 bytes shorter, and the
difference is before the values that need changing). That Surely Works™.

Subject: HID: add support for Huion 580 tablet

Add hid-huion.c with support for Huion 580 tablet, which is simple
8x5" tablet with 4000LPI resolution and 2048 levels pressure-sensitive
pen manufactured by the Chinese company Huion.

The driver fixes incorrect report descriptor sent by the device,
performs custom initialization required to switch the tablet into
its native resolution mode and inverts the in-range bit.

Subject: HID: add driver for ELO 4000/4500

This is a driver for ELO 4000/4500 devices which report themselves as
HID devices, but do not really send HID events on touch. So we
introduce a new HID 'quirk' driver with a raw_event handler where we
take care of those events.

What we need additionally is an input_configured hook, because the
device does not mention anything about PRESSURE and TOUCH in its
report descriptor, but it actually generate those. So we set the bits
in the corresponding input_dev in that hook.

Thanks to Petr Ostadal who was willing to test the driver. The rest of
Cc's listed below had something to do with that driver over the years
in our enterprise tree.

Subject: HID: elo: add quirks for broken firmware

One firmare version in the devices the driver takes care of is
completely broken and needs periodic pokes from our side. We
implemented this as a periodic delayed queue. The idea of the pokes
was taken from the suse enterprise kernel, in particular from Libor's
"Elo touchscreen firmware M workaround".

I am quoting him here:
  This patch adds periodic polling of the Elo USB touchscreens. Needed
  as a workaround for devices with M-level firmware, otherwise these
  devices are known to misbehave (as reported by Elo developers).

Subject: HID: Bluetooth: hidp: register HID devices async

While l2cap_user callbacks are running, the whole hci_dev is locked. Even
if we would add more fine-grained locking to HCI core, it would still be
called from the non-reentrant rx work-queue and thus block the event
processing.

However, if we want to perform synchronous I/O during HID device
registration (eg., to perform device-detection), we need the HCI core
to be able to dispatch incoming data.

Therefore, we now move device-registration to a separate worker. The HCI
core can continue running and we add devices asynchronously in another
kernel thread. Device removal is synchronized and waits for the worker
to exit before calling the usual device removal functions.

If l2cap_user->remove is called before the thread registered the devices,
we set "terminate" to true and the thread will skip it. If
l2cap_user->remove is called after it, we notice this as the device
is no longer in HIDP_SESSION_PREPARING state and simply unregister the
device as we did before.
There is no new deadlock as we now call hidp_session_add_dev() with
one lock less held (the HCI lock) and it cannot itself call back into
HCI as it was called with the HCI-lock held before.

One might wonder whether this can block during device unregistration.
But we set "terminate" to true and wake the HIDP thread up _before_
unregistering the HID/input devices. Therefore, all pending HID I/O
operations are canceled. All further I/O attempts will fail with ENODEV
or EIO. So all latency we can get are few context-switches, but no
timeouts or blocking I/O waits!

This change also prepares for a long standing HID bug. All HID devices
that register power_supply devices need to be able to handle callbacks
during registration (a power_supply oddity that cannot easily be fixed).
So with this patch available, we can allow HID I/O during registration
by calling the recently introduced hid_device_io_start/stop helpers,
which currently are a no-op for bluetooth due to this locking.

Note that we cannot do the same for input devices. input-core doesn't
allow us to call input_event() asynchronously to input_register_device(),
which HID-core kindly allows (for good reasons).
Fixing input-core to allow this isn't as easy as it sounds and is,
besid
