From 24705fd3f390c02757b23765db9a25d090f99faa Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 6 Apr 2022 09:40:14 +0300 Subject: [PATCH] OPP: call of_node_put() on error path in _bandwidth_supported() [ Upstream commit 907ed123b9d096c73e9361f6cd4097f0691497f2 ] This code does not call of_node_put(opp_np) if of_get_next_available_child() returns NULL. But it should.
