Subject: [PATCH v2 09/14] KVM: SVM: Unconditionally invoke sev_hardware_teardown()
Date: Wed, 13 Jan 2021 16:37:03 -0800 [thread overview]
Message-ID: <20210114003708.3798992-10-seanjc@google.com> (raw)
In-Reply-To: <20210114003708.3798992-1-seanjc@google.com>
Remove the redundant svm_sev_enabled() check when calling
sev_hardware_teardown(), the teardown helper itself does the check.
Removing the check from svm.c will eventually allow dropping
svm_sev_enabled() entirely.
No functional change intended.
