From 0618c077a8c20e8c81e367988f70f7e32bb5a717 Mon Sep 17 00:00:00 2001 From: Zhang Shurong Date: Thu, 5 Oct 2023 22:28:35 +0800 Subject: dmaengine: ste_dma40: Fix PM disable depth imbalance in d40_probe 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. We fix it by calling pm_runtime_disable when error returns.
