Subject: [PATCH 04/19] KVM: x86/tdp_mmu: Remove unused "kvm" of kvm_tdp_mmu_get_root()
Date: Tue, 25 Jan 2022 17:58:54 +0800	[thread overview]
Message-ID: <20220125095909.38122-5-cloudliang@tencent.com> (raw)
In-Reply-To: <20220125095909.38122-1-cloudliang@tencent.com>

From: Jinrong Liang <cloudliang@tencent.com>

The "struct kvm *kvm" parameter of kvm_tdp_mmu_get_root() is not used,
so remove it. No functional change intended.
