[PATCH v2 012/144] KVM: selftests: Use vcpu_access_device_attr() in arm64 code

From: Sean Christopherson
Date: Thu Jun 02 2022 - 20:45:19 EST


Use vcpu_access_device_attr() in arm's arch_timer test instead of
manually retrieving the vCPU's fd. This will allow dropping vcpu_get_fd()
in a future patch.
