The patch there still has at least one issue I guess - the keycodes[] allocation size should be MATRIX_MAX_ROWS * MATRIX_MAX_COLS if I understand correctly. I'm experiencing a problem of keypad->pdata being overwritten, and found keycodes are actually accessed by [(row << 4) + col], so that should be a full range. And one more minor issue that may not be significant is the hardcoding of the '4' in this (row << 4). Some of the key hits on my Littleton just worked smoothly with the above correction, but not all - some key hits just gave intermittent events, I have no idea how's that - maybe related to my scan delay and debouncing settings > Thanks! > -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
