From 8a065ce92b218e453742b745162d75a6f86fb768 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Tue, 20 Apr 2021 21:31:51 +0200 Subject: regulator: Avoid a double 'of_node_get' in 'regulator_of_get_init_node()' 'for_each_available_child_of_node()' already performs an 'of_node_get()' on child, so there is no need to perform another one before returning. Otherwise, a double 'get' is performed and a resource may never be released.
