From fe6df2b48043bbe1e852b2320501d3b169363c35 Mon Sep 17 00:00:00 2001 From: Dinghao Liu Date: Wed, 7 Apr 2021 13:11:49 +0800 Subject: [PATCH] mfd: arizona: Fix rumtime PM imbalance on error pm_runtime_get_sync() will increase the rumtime PM counter even it returns an error. Thus a pairing decrement is needed to prevent refcount leak. Fix this by replacing this API with pm_runtime_resume_and_get(), which will not change the runtime PM counter on error.
