Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: rockchip: Fix PM usage reference of rockchip_i2s_tdm_resume
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 pm_runtime_resume_and_get to keep usage counter balanced.
