[PATCH v5 11/15] KVM: SVM: Explicitly check max SEV ASID during sev_hardware_setup()
From: Sean Christopherson
Date: Wed Apr 21 2021 - 22:12:16 EST
Query max_sev_asid directly after setting it instead of bouncing through
its wrapper, svm_sev_enabled(). Using the wrapper is unnecessary
obfuscation.
No functional change intended.
