Added STM sensor hub new device id. Also added this new device
in HID_SENSOR_HUB_ENUM_QUIRK to fix report descriptors.
These devices uses old FW which uses logical 0 as minimum.
In these, HID reports are not using proper collection classes.
So we need to fix report descriptors,for such devices. This
will not have any impact, if the FW uses logical 1 as minimum.

The device which identifies itself as a "USB Keykoard" (no typo) with VID:PID
1a2c:0023 does not seem to be handling the reports initialization very well.
This results in a "usb_submit_urb(ctrl) failed: -1" message from the kernel
when connected, and a delay before its initialization. This patch adds the
quirk for this device, which causes the delay to disappear.

Some saitek mice implement a tristate button (for switching button mappings in
the original driver) by keeping one of three (non-physical)
buttons constantly pressed.
This breaks X and probably other userspace software.
This patch implements a quirk for the R.A.T.7 and M.M.O.7, tracking the mode
and generating presses of a single button if it changes. Also the missing
release event is generated instantly.

Some drivers use the first HID report in the list instead of using an
index. In these cases, validation uses ID 0, which was supposed to mean
"first known report". This fixes the problem, which was causing at least
the lgff family of devices to stop working since hid_validate_values
was being called with ID 0, but the devices used single numbered IDs
for their reports:
0x05, 0x01, /* Usage Page (Desktop), */
0x09, 0x05, /* Usage (Gamepad), */
0xA1, 0x01, /* Collection (Application), */
0xA1, 0x02, /* Collection (Logical), */
0x85, 0x01, /* Report ID (1), */

The F11 data in the HID report contains four bits of data for w_x and the least significant bits
of x. Currently only the first three bits are being used which is resulting in small jumps in
the position data on the x axis and in the w_x data.

A firmware bug is present on the XPS Haswell edition which silently
split the request in two responses when the caller ask for a read of
more than 16 bytes.
The FW sends the first 16 then the 4 next, but it says that it answered
the 20 bytes in the first report.
This occurs only on the retrieving of the min/max of X and Y of the F11
function.
We only use the first 10 bytes of the Ctrl register, so we can get only
those 10 bytes to prevent the bug from happening.

Reading the partial HID Descriptor is causing a firmware lockup in some
sensor hubs. Instead of a partial read, this patch implements the
i2c hid fetch using a fixed descriptor size (30 bytes) followed by a
verification of the BCDVersion (V01.00), and value stored in
wHIDDescLength (30 Bytes) for V1.00 descriptors.
As per i2c hid spec, this is the preferred model.
From hid-over-i2c-protocol-spec-v1-0:
There are a variety of ways a HOST may choose to retrieve
the HID Descriptor from the DEVICE. The following is a preferred
implementation but should not be considered the only implementation.
A HOST may read the entire HID Descriptor in a single read by
issuing a read for 30 Bytes to get the entire HID Descriptor
from the DEVICE.However, the HOST is responsible for validating that
1. The BCDVersion is V01.00 (later revisions may have different
descriptor lengths), and
2. The value stored in wHIDDescLength is 30 (Bytes) for V1.00
descriptors.

The extra seven bits are only required when allocating the report buffer.
We can not use those extra bytes for the length of the report in the
generic implementation of .request because the device might (will) refuse
the set_report command.
This has been verified on the Atmel touchpad found on the Samsung Ativ 9
plus, which uses hid-multitouch and HID over I2C. Without this fix, the
device refuses to switch to the multitouch mode, and it becomes unresponsive
from the user point of view.
Actually, this has been discussed during the initial submission of the
commit 4fa5a7f76c, see
https://patchwork.kernel.org/patch/3621751/
Unfortunately, I completely forgot about it later.

Add support for setting the blink rate of the LEDs. The Sixaxis allows control
over each individual LED, but the Dualshock 4 only has one global control for
controlling the hardware blink rate so individual colors will fall back to
software timers.
Setting the brightness cancels the blinking as per the LED class specifications.
The Sixaxis and Dualshock 4 controllers accept delays in decisecond increments
from 0 to 255 (2550 milliseconds).
The value at index 1 of the DualShock 4 USB output report must be 0xFF or the
light bar won't blink.

Add an IDA id allocator to assign unique, sequential device ids to Sixaxis and
DualShock 4 controllers.
Use the device ID to initialize the Sixaxis and DualShock 4 controller LEDs to
default values. The number or color of the controller is set relative to other
connected Sony controllers.
Set the LED class brightness values to the initial values and add the new led to
the array before calling led_classdev_register so that the correct brightness
value shows up in the LED sysfs entry.
Use explicit module init and exit functions since the IDA allocator must be
manually destroyed when the module is unloaded.
