[PATCH 5/6] input: adc-keys: use device_for_each_child_node_scoped()

From: Javier Carrasco
Date: Fri Apr 12 2024 - 16:58:52 EST


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.
