I have recently acquired a cheap Apollo Lake-based laptop that uses a
Hynitron CST128-A touchpad controller. While booting from a Debian LiveCD,
the kernel log is flooded with the following error (though the touchpad
works well):

  i2c_hid_acpi i2c-ALPS0001:00: i2c_hid_get_input: incomplete report (27/42405)

The CST128-A was identified via ACPI as ALPS0001:00, and the I2C HID
device ID (0911:5288) was shared with the Hantick 5288.

Add the I2C_HID_QUIRK_BAD_INPUT_SIZE quirk option to the existing Hantick
5288 quirk entry to suppress the kernel log flood.
