From 01c972a33cae0743c799a3a9b86d8a8dfdf22a94 Mon Sep 17 00:00:00 2001 From: Zhang Qilong Date: Tue, 8 Nov 2022 16:03:21 +0800 Subject: [PATCH] soc: ti: knav_qmss_queue: Fix PM disable depth imbalance in knav_queue_probe [ Upstream commit e961c0f19450fd4a26bd043dd2979990bf12caf6 ] The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced according to context.
