Summary
drm/bridge: Add missing pm_runtime_put_sync
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/bridge: Add missing pmruntimeput_sync

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 pmruntimeresumeand_get(), 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.
