In the Linux kernel, the following vulnerability has been resolved: drm/bridge: Add missing pmruntimeputsync pmruntimegetsync() will increase the rumtime PM counter even when it returns an error. Thus a pairing decrement is needed to prevent refcount leak. Fix this by replacing this API with pmruntimeresumeandget(), which will not change the runtime PM counter on error. Besides, a matching decrement is needed on the error handling path to keep the counter balanced.
