From 58e4aacb746321d8692996f40a1dcfb9e8b34c23 Mon Sep 17 00:00:00 2001 From: Vincent Whitchurch Date: Fri, 15 Sep 2023 09:02:14 +0200 Subject: power: supply: Propagate of_node to child device Ensure that the dynamically created power supply device sets its ->of_node if the driver supplies one. This brings it in line with several other subsystems (see git grep 'of_node =.*parent.*of_node') and allows easier identification of the device from udev rules and similar.
