Subject: [PATCH 1/6] input: iqs269a: use
 device_for_each_child_node_scoped()

Switch to the _scoped() version introduced in commit 365130fd47af
("device property: Introduce device_for_each_child_node_scoped()")
to remove the need for manual calling of fwnode_handle_put() in the
paths where the code exits the loop early.
