CVE-2025-38421

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

platform/x86/amd: pmf: Use device managed allocations

If setting up smart PC fails for any reason then this can lead to
a double free when unloading amd-pmf.  This is because dev->buf was
freed but never set to NULL and is again freed in amd_pmf_remove().

To avoid subtle allocation bugs in failures leading to a double free
change all allocations into device managed allocations.
