Subject: [PATCH v2 7/7] KVM: VMX: Use local pointer to vcpu_vmx in vmx_vcpu_after_set_cpuid()
Date: Fri,  4 Feb 2022 20:47:05 +0000	[thread overview]
Message-ID: <20220204204705.3538240-8-oupton@google.com> (raw)
In-Reply-To: <20220204204705.3538240-1-oupton@google.com>

There is a local that contains a pointer to vcpu_vmx already. Just use
that instead to get at the structure directly instead of doing pointer
arithmetic.

No functional change intended.
