Subject: [PATCH 0/6] input: 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. This modification simplifies
the code and eliminates the risk of leaking memory if any early exit is
added without de-allocating the child node.

There are six users of the non-scoped version in the input subsystem:

- iqs269a
- qt1050
- gpio_keys
- gpio_keys_polled
- adc-keys
- adc-joystick

This series is based on the master branch of linux-next (next-20240412)
to have access to the scoped version of device_for_each_child_node().
