The patch that added Logitech Dual Action gamepad support forgot to
update the special driver list for the device. This caused the logitech
driver not to probe unless kernel module load order was favorable.
Update the special driver list to fix it. Thanks to Simon Wood for the
idea.

Plugging a Logitech DJ receiver with KASAN activated raises a bunch of
out-of-bound readings.

The fields are allocated up to MAX_USAGE, meaning that potentially, we do
not have enough fields to fit the incoming values.
Add checks and silence KASAN.

extract() and implement() access buffer containing reports in 64-bit
chunks, but there is no guarantee that buffers are padded to 64 bit
boundary. In fact, KASAN has caught such OOB access with i2c-hid and
Synaptics touch controller.

Instead of trying to hunt all parties that allocate buffers and make
sure they are padded, let's switch extract() and implement() to byte
access. It is a bit slower, bit we are not dealing with super fast
devices here.

Also let's fix link to the HID spec while we are at it.

Now, PM core supports asynchronous suspend/resume mode for devices
during system suspend/resume, and the power state transition of one
device may be completed in separate kernel thread. PM core ensures
all power state transition timing dependency between devices. This
patch enables hid devices to suspend/resume asynchronously. This
will take advantage of multicore and improve system suspend/resume
speed.

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.

Once there were kernel drivers for some of the phidgets devices, and for
those kernel drivers to work the hid system needed exceptions. Now the
kernel drivers are long gone in favour of the user-space drivers.

The user-space drivers support many more phidget devices and uses libusb.
The udev rules set up permissions so that the kernel hid driver can be
unbound from libusb, as it does for many devices not in hid_ignore_list.

member of hid_device structure. It identifies the country code of localized
hardware.

For example some keyboards use it to exhibit the language of the key layout. It
helps the upper layer to identify the localized hardware and setup the correct
language to use.

For USB HID devices the country code comes for the HID descriptor and for
Bluetooth HID devices it is the HIDCountryCode attribute from the SDP database.
