Description OSIDB Bzimport 2025-09-18 17:03:40 UTC 
In the Linux kernel, the following vulnerability has been resolved:

mfd: arizona: Use pm_runtime_resume_and_get() to prevent refcnt leak

In arizona_clk32k_enable(), we should use pm_runtime_resume_and_get()
as pm_runtime_get_sync() will increase the refcnt even when it
returns an error.
