Make sure calibration values are defined to prevent potential kernel
crashes. This fixes a hypothetical issue for virtual or clone devices
inspired by a similar fix for DS4.

Some DualShock4 devices report invalid calibration data resulting
in kernel oopses due to division by zero during report handling.
The devices affected generally appear to be clone devices, which don't
implement all reports properly and don't populate proper calibration
data. The issue may have been seen on an official device with erased
calibration reports.
This patch prevents the crashes by essentially disabling calibration
when invalid values are detected.

The 'buf' variable is only used in the USB (if-path) and not in the Bluetooth
else-path. Since it is not set to NULL. this results in freeing an uninitialized
pointer. Since the else code-path doesn't need buf, just return 0.

The driver was by accident reading the CRC directly from a hardware

The size of the output buffer used for output reports was not updated
to the larger size needed for Bluetooth. This ultimately resulted
in memory corruption of surrounding structures e.g. due to memsets.

This patch adds support for the DualShock4 dongle in a very similar
way we contributed to hid-sony before.
The dongle is a USB to Bluetooth bridge and uses the same HID reports
as a USB device. It reports data through the DS4's main USB input
report independent on whether a Bluetooth controller is connected.
For this reason there is custom dongle report parsing code to
detect controller hotplug and kick of calibration work until we
are ready to process actual input reports.
The logic also incorporates a workaround needed for Steam in which
hid-playstation and Steam using hidraw can fight.

Add support for DualShock4 in Bluetooth mode. In Bluetooth, the device
is a bit strange in that after 'calibration' it switches sending all its
input data from a basic report (only containing buttons/sticks) to an
extended report, which also contains touchpad, motion sensors and other
data. The overall design of this code is similar to the DualSense code.

Expose the lightbar LEDs in the same manner as hid-sony through
individual LEDs for backwards compatibility reasons. There is a
slight change in LED naming to use the input device name as opposed
to the MAC address like hid-sony did. This is expected to not
cause any issues and should make the naming more compliant.
In addition set a default lightbar color based on player ID.

There is no need for a driver to individually add/create device groups,
the driver core will do it automatically for you. Convert the
hid-playstation driver to use the dev_groups pointer instead of manually
calling the driver core to create the group and have it be cleaned up
later on by the devm core.

The DualSense controller has a built-in microphone exposed as an
audio device over USB (or HID using Bluetooth). A dedicated

The DualSense features a haptics system based on voicecoil motors,
which requires PCM data (or special HID packets using Bluetooth). There
is no appropriate API yet in the Linux kernel to expose these. The
controller also provides a classic rumble feature for backwards
compatibility. Expose this classic rumble feature using the FF framework.

This patch adds support for the DualSense when operating in Bluetooth mode.
The device has the same behavior as the DualShock 4 in that by default it
sends a limited input report (0x1), but after requesting calibration data,
it switches to an extended input report (report 49), which adds data for
touchpad, motion sensors, battery and more.
