[ Upstream commit e45d7337dc0e4f7f1c2876e1b22c71a544ad12fd ]
In anx7411_typec_switch_probe(), we should call of_get_child_by_name()
instead of of_find_node_by_name() as of_find_xxx API will decrease the
refcount of the 'from' argument.
Fixes: fe6d8a9c8e64 ("usb: typec: anx7411: Add Analogix PD ANX7411 support")
