CVE-2022-49128
drm/bridge: Add missing pm_runtime_put_sync
In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: Add missing pm_runtime_put_sync
pm_runtime_get_sync() 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
pm_runtime_resume_and_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.
