CVE-2026-97473

powercap: intel_rapl: Fix memory leak in rapl_add_package_cpuslocked()

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

powercap: intel_rapl: Fix memory leak in rapl_add_package_cpuslocked()

When topology_physical_package_id()/topology_logical_die_id() returns
a negative value, rapl_add_package_cpuslocked() returns ERR_PTR(-EINVAL)
directly without freeing the rapl_package structure that was just
allocated by kzalloc_obj(), leaking memory on every failed package
addition.

Use the existing err_free_package label so that the allocation is
released on the error path.
