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.

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.

This makes sure IO is never restarted while a reset is going on
In particular there seems to be no protection from hid_retry_timeout() calling
hid_start_in() which would start IO after hid_pre_reset() has already called
hid_cease_io() because that uses del_timer(), not del_timer_sync()

We shouldn't change the event flags of input devices after they get registered.
Otherwise, udev will not get notified of these flags and cannot setup the
devices properly.
This fixes the probing to set the input event flags on the input_mapped callback
instead of the probe function.

Now that hid-generic ignores all win7 compatible multitouch devices, this patch
allows hid-multitouch to catch them. The idea is to rely on the quirk
HID_QUIRK_MULTITOUCH to drop the device if no ContactID is given.
There is the need for a blacklist here as other devices may need a special
driver (ntrig for instance).

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.

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.

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.

To initialize wiimote peripherals, the stream to the wiimote must be held
exclusively by the initializer, otherwise the initialization will fail. Many
initializations require multiple memory requests to be sent synchronously so we
need a way to lock the stream and release it when we are done.
This adds several helper functions which allow to lock the stream, then send
requests, wait for the answers and release the stream again.
When holding the lock, the function may sleep and interrupted by signals.
Also it returns after a short timeout so userspace shouldn't notice long
delays.

Add parser functions for accelerometer data reported by the wiimote. The data is
almost always reported in the same format, so we can use a single handler.
However, an own handler function is created for each DRM-mode because when IR
and extension support is added, each of them is parsed differently.
Also set the appropriate DRM including accelerometer data on DRM requests to
actually retrieve the accelerometer data.
Data is reported to userspace as ABS_RX/Y/Z values. The values are between -500
and 500 and 0 means no acceleration. See also userspace xwiimote library for
data parsing.

The wiimote has a single rumble motor. This adds force feedback support for
