The SHANWAN PS3 clone joypad will start its rumble motors as soon as
it is plugged in via USB. As the additional USB interrupt does nothing on
the original PS3 Sixaxis joypads, and makes a number of other
clone joypads actually start sending data, disable that call for
the SHANWAN so the rumble motors aren't started on plug.

Several cheap Apollo Lake based laptops / 2-in-1s use an i2c-hid mt
touchpad which is advertised by the DSDT with an ACPI HID of "SYNA3602",
this touchpad can be found on e.g. the Cube Thinker and the EZBook 3 Pro.

On my "T-bao Tbook air" the i2c-hid driver fails to bind to this touchpad:
"i2c_hid i2c-SYNA3602:00: failed to reset device.".

After some debuging this it seems that this touchpad simply never sends
an interrupt after a reset as expected by the i2c hid driver. This commit
adds a quirk for this device, making i2c_hid_command sleep 100ms after
a reset instead of waiting for an irq, fixing i2c-hid failing to bind to
this touchpad.

The WACOM_PEN_FIELD macro is used to determine if a given HID field should be
associated with pen input. This field includes several known collection types
that Wacom pen data is contained in, but the WACOM_HID_WD_PEN application
collection type is notably missing. This can result in fields within this
kind of collection being completely ignored by the `wacom_usage_mapping`
function, preventing the later '*_event' functions from being notified about
changes to their value.

The hid-rmi driver may handle non rmi devices on composite USB devices.

The hid descriptor identifies the length and type of subordinate
descriptors for a device. If the received hid descriptor is smaller than
the size of the struct hid_descriptor, it is possible to cause
out-of-bounds.

In addition, if bNumDescriptors of the hid descriptor have an incorrect
value, this can also cause out-of-bounds while approaching hdesc->desc[n].

So check the size of hid descriptor and bNumDescriptors.
