[1/2] hwmon: (ltc2991) use device_for_each_child_node_scoped()

Commit Message

Javier Carrasco April 4, 2024, 11:13 a.m. UTC

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.
