If anyone has any objections, please let me know. ------------------ From: Youth Cao [ Upstream commit 58d97b45f3f43af0afd9c74e8480d22d36fd3f72 ] 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.
