Linux amd-pstate - memory leak in amd_pstate_epp_cpu_init(): On failure to set the energy-performance preference

Impact

On failure to set the energy-performance preference, amd_pstate_epp_cpu_init() returns without freeing what it allocated. Another slow leak in the AMD CPU frequency driver, hit on the error path - which is the path a misconfigured or partially-supported platform takes repeatedly rather than once.

Who can reach it

Local, on the amd-pstate initialisation error path.

What to do

Distro kernel update plus reboot. Batch with the other amd-pstate fixes.
