From 6d2d2aaae1faa64c2f803d6f11f4b2df3b3c2cff Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Fri, 26 Apr 2024 10:30:33 -0500 Subject: [PATCH] ASoC: da7219-aad: fix usage of device_get_named_child_node() [ Upstream commit e8a6a5ad73acbafd98e8fd3f0cbf6e379771bb76 ] The documentation for device_get_named_child_node() mentions this important point: " The caller is responsible for calling fwnode_handle_put() on the returned fwnode pointer. " Add fwnode_handle_put() to avoid a leaked reference.
