Also remove the shared resource workaround by moving the pinctrl entry for the trackpad interrupt line back into the individual trackpad nodes. Signed-off-by: Chen-Yu Tsai --- Changes since v6: None. Changes since v5: None. Changes since v4: - Rebased Changes since v3: - Also remove second source workaround, i.e. move the interrupt line pinctrl entry from the i2c node back to the components.
