Benjamin Tissoires b1807719f6 HID: Correct General touch PID
Genera Touch told us that 0001 is their single point device
and 0003 is the multitouch one. Apparently, we made the tests
someone having a prototype, and not the final product.
They said it should be safe to do the switch.

This partially reverts 5572da0 ("HID: hid-mulitouch: add support
for the 'Sensing Win7-TwoFinger'").

Linus Torvalds 21404b772a hid/apple: modern macbook airs use the standard apple function key translations
This removes the use of the special "macbookair_fn_keys" keyboard
translation table for the MacBookAir4,x models (ie the 2011 refresh).
They use the standard apple_fn_keys[] translation.  Apparently only the
old MacBook Air's need a different translation table.

This mirrors the change that commit da617c7cb9 ("HID: consolidate
MacbookAir 4,1 mappings") did for the WELLSPRING6A ones, but does it for
the WELLSPRING6 model used on the MacBookAir4,2.

This reverts commit 0db3bfc72a (""HID: multitouch: decide if hid-multitouch
needs to handle mt devices").

The generic detection of hid-mt devices has two major flaws, and was
merged prematurely. Firstly, the hid-multitouch gets loaded even when
the device is handled by a special device. Secondly, the patch only
partially duplicates the device whitelist already present in hid-core,
effectively rendering a number of devices non-functional.

Julia Lawall 8052ee5f5f HID: drivers/hid/hid-roccat.c: eliminate a null pointer dereference
It is not possible to take the lock in device if device is NULL.
The mutex_lock is thus moved after the NULL test.  New error handling
labels are added at the end to differentiate between the cases where
different sets of locks should be unlocks, and between whether or not
reader should be freed (only on error).

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
expression E, E1;
identifier f;
statement S1,S2,S3;

Daniel van Vugt bca621421c HID: hid-magicmouse: Magic Trackpad has 1 button, not 2
hid-magicmouse was advertising the Apple Magic Trackpad as having 2
buttons (left and right) when it actually only has 1 button.

Advertising multiple buttons makes Xorg disable all button 2 and 3
emulation (using multi-finger clicks). So Xorg users don't get working
right/middle-click emulation out of the box.

This patch makes hid-magicmouse correctly only report one real button
for Magic Trackpad, which in turn makes Xorg enable multi-finger click
support to emulate right/middle buttons.

Terry Lambert f6a04605f3 HID: support primax keyboards violating USB HID spec
Primax keyboards with the issue this driver addresses report modifier
keys as in band key events instead of as out of band modifier bits,
resulting in the modifier keys generating key up events immediately
before the keys they are intended to modify.  This driver rewrites
the raw report data from such keyboards into USB HID 1.11 compliant
report data.  It only matches the USB vendor and product IDs for the
keyboard it has been tested on. Since there are several keyboards,
notably a number of laptops and folding USB keyboards known to have
similar unresolved problem reports, the list is expected to grow.

James Hogan 65b01bd561 HID: hidraw: protect hidraw_disconnect() better
The function hidraw_disconnect() only acquires the hidraw minors_lock
when clearing the entry in hidraw_table. However the device_destroy()
call can cause a userland read/write to return with an error. It may
cause the program to release the file descripter before the disconnect
is finished. hidraw_disconnect() has already set hidraw->exist to 0,
which makes hidraw_release() kfree the hidraw structure, which
hidraw_disconnect() continues to access and even tries to kfree again.
Similarly if a hidraw_release() occurs after setting hidraw->exist to 0,
the same thing can happen.

This is fixed by expanding the mutex critical section to cover the whole
function from setting hidraw->exist to 0 to freeing the hidraw
structure, preventing a hidraw_release() from interfering.

Nestor Lopez Casado 534a7b8e10 HID: Add full support for Logitech Unifying receivers
With this driver, all the devices paired to a single Unifying
receiver are exposed to user processes in separated /input/dev
nodes.

Keyboards with different layouts can be treated differently,
Multiplayer games on single PC (like home theater PC) can
differentiate input coming from different kbds paired to the
same receiver.

Up to now, when Logitech Unifying receivers are connected to a
Linux based system, a single keyboard and a single mouse are
presented to the HID Layer, even if the Unifying receiver can
pair up to six compatible devices. The Unifying receiver by default
multiplexes all incoming events (from multiple keyboards/mice)
into these two.

David Herrmann 9086617ea3 HID: wacom: Unregister sysfs attributes on remove
HID devices can be hotplugged so we should unregister all sysfs attributes when
removing a driver. Otherwise, manually unloading the wacom-driver will not
remove the sysfs attributes. Only when the device is disconnected, they are
removed, eventually.

David Herrmann dde58cfcc3 HID: wacom: Fix error path of power-supply initialization
power_supply_unregister() must not be called if power_supply_register() failed.
The wdata->psy.dev pointer may point to invalid memory after a failed
power_supply_register() and hence wacom_remove() will fail while calling
power_supply_unregister().

This changes the wacom_probe function to fail if it cannot register the
power_supply devices. If we would want to keep the previous behaviour we had to
keep some flag about the power_supply state and check it on wacom_remove, but
this seems inappropriate here. Hence, we simply fail, too, if
power_supply_register fails.

David Herrmann 6591d758d5 HID: wiimote: Read wiimote battery charge level
This registers a power_supply device for every remote to retrieve the current
battery charge level. Since this information is not sent by the wiimote
continously, we need to explicitely request it.

The wiimote does not send status reports continuously so this adds a helper
function to request a status report and parses the battery charge level.
