(edge-falling). I do not believe this is right solution. The driver makes liberal use of disable_irq() and enable_irq() which may lead to lost edges and touchpad stopping working altogether. Usually the "extra" report is caused by GPIO controller clearing interrupt condition at the wrong time (too early), or in unsafe or racy fashion. You need to look there instead of adding quirk to i2c-hid. Thanks. -- Dmitry
