But the only in-tree user of SEV/SNP functionality is KVM, and KVM depends on PSP driver for the same. Forcing SEV/SNP initialization because a hypervisor could be running legacy non-confidential VMs make no sense. This patch removes SEV/SNP initialization from the PSP driver probe time and moves the requirement to initialize SEV/SNP functionality to KVM if it wants to use SEV/SNP.
