Description

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.
