In case the requested gpio property is not found in the device tree, some
callers of gpiod_get_from_of_node() expect a return value of NULL, others
expect -ENOENT.
In particular devm_fwnode_get_index_gpiod_from_child() expects -ENOENT.
Currently it gets a NULL, which breaks the loop that tries all

By setting the SION bit the actual status of a gpio pin can be read back
regardless of its driver configuration.
You can drop my patch as there i
