hidpp_scroll_counter_handle_scroll() doesn't expect a 0-value scroll event, it
gets interpreted as a negative scroll direction event. This can cause scroll
direction resets and thus broken scrolling.
Fixes: 4435ff2f09a2fc ("HID: logitech: Enable high-resolution scrolling on Logitech mice")

create_singlethread_workqueue may fail and return NULL. The fix checks if it is
NULL to avoid NULL pointer dereference. Also, the fix moves the call of
create_singlethread_workqueue earlier to avoid resource-release issues.

There are three features used by various Logitech mice for
high-resolution scrolling: the scrolling acceleration bit in HID++ 1.0,
and the x2120 and x2121 features in HID++ 2.0 and above. This patch
supports all three, and uses the multiplier reported by the mouse for
the HID++ 2.0+ features.
The full list of product IDs of mice which support high-resolution
scrolling was provided by Logitech, but the patch was tested using the
following mice (using the Unifying receiver):
* HID++ 1.0: Anywhere MX, Performance MX
* x2120: M560
* x2121: MX Anywhere 2, MX Master 2S
This patch is a combinations of the now-reverted commits 1ff2e1a44e0,
d56ca9855bf9, 5fe2ccbef9d, 044ee89028 together with some extra bits for the
directional and timeout-based reset.
The previous patch series was in hid-input, it appears this remainder
handling is logitech-specific and was moved to hid-logitech-hidpp.c and
renamed accordingly.

CAPACITY LEVEL allows to forward rough information on the battery mileage.
HID++ 2.0 devices will either report percentage or levels, so better
forwarding this information to the user space.
The M325 supports only 2 levels: 'Full' and 'Critical'. With mileage,
it will report either 90% or 5%, which might confuse users. With this
change the battery will either report "Full" or "Critical".

Unifying devices are different from others because they can probed
while not connected. So we need to talk to the receiver to get some
extra information like the device name and the serial.
Instead of having conditionals while attempting to read the device name
from HID++ 2.0, have a special init path for them.
Store the retrieved serial in hdev->uniq.

This patch implements force feedback support for the Logitech
G920 Driving Force Racing Wheel. It is a generic implementation
of feature 0x8123 of the Logitech HID++ protocol and should be
usable for any future devices that implement this feature.
This patch should be applied after the basic G920 support patch
by Simon Wood:
http://www.spinics.net/lists/linux-input/msg42174.html
The driving supports everything that is supported by the G920
firmware:
FF_CONSTANT
FF_PERIODIC
FF_SINE
FF_SQUARE
FF_SAW_UP
FF_SAW_DOWN
FF_TRIANGLE
FF_SPRING
FF_DAMPER
FF_AUTOCENTER
FF_GAIN
and for version 2 firmware also:
FF_FRICTION
FF_INERTIA
FF_RAMP
Both envelopes and replay values are supported as well, but some
problems may occur when using firmware release 1. There is also a
small residual clockwise damper in the wheel when using the first
firmware release. All problems are fixed in the soon te be released
firmware version 2.
The default spring is disabled by permanently placing a spring
force in the wheel. This spring is also used as the autocenter
spring.
Note: The wheel _DOES_NOT_ auto switch to Logitech/HID mode (it is stuck
in XBox since the xpad changes where not included). Michal has an
alternative approach documented here (and the changes should be submitted
upstream to usb_modeswitch project):
===
Create a file named "046d:c261" in "/etc/usb_modeswitch.d" with the
following content:
DefaultVendor=046d
DefaultProduct=c261
MessageEndpoint=01
ResponseEndpoint=01
TargetClass=0x03
MessageContent="0f00010142"
Then run "usb_modeswitch -c /etc/modeswitch.d/046d:c291" as root and
watch the magic happen:)

This patch adds basic support for the Logitech G920 wheel when in HID
mode. This wheel 'speaks' the HID++ protocol, and therefor is driven
with hid-logitech-hidpp.
At this stage the driver only shows that it can communicate with the
wheel by outputting the name discovered over HID++.
The normal HID functions work to give input functionality using
joystick/event interface.
Note: in 'hidpp_probe()' we have to start the hardware to get packets
flowing, the same might apply in future for other devices which don't
use the unifying protocol.

The Logitech M560 is a wireless mouse designed for windows 8 which uses
the unifying receiver.
Compared to a standard one, some buttons (the middle one and the
two ones placed on the side) are bound to a key combination
instead of a generating classic "mouse" button events.
The device shows up as a mouse and keyboard combination: when the middle
button is pressed it sends a key (as keyboard) combination, the same
happens for the two side button. The left/right/wheel work as expected
from a mouse. To complicate things further, the middle button sends
different keys combinations between odd and even presses.
In the "even" press it also sends a left click. But the worst thing
is that no event is generated when the middle button is released.
It is possible to re-configure the mouse sending a command (see function
m560_send_config_command()). After this command the mouse sends some
useful data when the buttons are pressed and/or released.
