Description
In the Linux kernel, the following vulnerability has been resolved: drm/rockchip: lvds: fix PM usage counter unbalance in poweron pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. We fix it by replacing it with the newest pm_runtime_resume_and_get to keep usage counter balanced.
