From d0675b67b42eb4f1a840d1513b5b00f78312f833 Mon Sep 17 00:00:00 2001 From: Qiushi Wu Date: Sun, 14 Jun 2020 01:27:12 +0200 Subject: media: camss: Fix a reference count leak. pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code, causing incorrect ref count if PM runtime put is not called in error handling paths. Thus call pm_runtime_put_sync() if pm_runtime_get_sync() fails.
