The IRQ is described as (Edge, ActiveLow, Shared, ) in ACPI DSDT and it's correct. The override makes the keyboard interrupt polarity inverted, resulting in non-functional keyboard. Add an entry for skipping the override.

Cc: stable@vger.kernel.org Signed-off-by: Chuanhong Guo gch981213@gmail.com --- Change since v1: Match DMI_PRODUCT_NAME for ThinkBook because the board name is used for other completely different Lenovo laptops.

Change since v2: fix alphabetical order in skip_override_table
