The latest gpio hogging mechanism assigns each gpio a 'line-name' in the devicetree. The 'name' field is different from the 'label' field. 'label' is only used for requested GPIOs to describe its current use by driver or userspace. The 'name' field describes the GPIO itself, not the use. This is most likely identical to the label in the schematic on the GPIO line and should help to find this particular GPIO.
