Description

In the Linux kernel, the following vulnerability has been resolved:

pmdomain: arm: scmi: Fix genpd leak on provider registration failure

If of_genpd_add_provider_onecell() fails during probe, the previously created generic power domains are not removed, leading to a memory leak and potential kernel crash later in genpd_debug_add().

Add proper error handling to unwind the initialized domains before returning from probe to ensure all resources are correctly released on failure.

Example crash trace observed without this fix:
