From: Wentao Liang Date: Wed, 27 May 2026 10:48:50 +0000 (+0000) Subject: regulator: scmi: fix of_node refcount leak in scmi_regulator_probe() X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=fa11039d6cdff84584a3ef8cc1f5e1b56e045da2;p=thirdparty%2Fkernel%2Flinux.git regulator: scmi: fix of_node refcount leak in scmi_regulator_probe() scmi_regulator_probe() calls of_find_node_by_name() which takes a reference on the returned device node. On the error path where process_scmi_regulator_of_node() fails, the function returns without calling of_node_put() on the child node, leaking the reference. Add of_node_put(np) on the error path to properly release the reference.
