This node should go before the keyboard node to maintain the sort order.
Also, none of the other labels have a "state" suffix and the other
active-low pin node names have a "-n" suffix.
So I believe this should be
hall_int_n: hall-int-n-state
for consistency.

Newline not needed (nor used in the other nodes).

Looks good otherwise and appears to work as intended:
