From: Miaoqian Lin <linmq006@gmail.com> stable inclusion from stable-v5.10.137 commit 97713ed9b6cc4abaa2dcc8357113c56520dc6d7f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I60PLB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit e6e0951414a314e7db3e9e24fd924b3e15515288 ] Every iteration of for_each_available_child_of_node() decrements the reference count of the previous node. When breaking early from a for_each_available_child_of_node() loop, we need to explicitly call of_node_put() on the child node. Add missing of_node_put() to avoid refcount leak.
