Description OSIDB Bzimport 2025-02-26 03:19:32 UTC 
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.
