6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peng Ma <andypma@xxxxxxxxxxx>
[ Upstream commit cea04f3d9aeebda9d9c063c0dfa71e739c322c81 ]
The cpudata memory from kzalloc() in amd_pstate_epp_cpu_init() is
not freed in the analogous exit function, so fix that.
