Subject: [PATCH] cpuidle: Fix reference count on CPU node
Date: Tue, 17 Sep 2024 23:13:25 +0200	[thread overview]
Message-ID: <20240917211325.639765-1-mikisabate@gmail.com> (raw)

For the qcom-spm driver, an early return was not calling the proper
of_node_put call for a previously acquired device node.
