From ad6d6b949e1d5a1475c4fc8400bd38aabea4f83c Mon Sep 17 00:00:00 2001 From: Jinrong Liang Date: Tue, 25 Jan 2022 17:58:54 +0800 Subject: [PATCH] KVM: x86/tdp_mmu: Remove unused "kvm" of kvm_tdp_mmu_get_root() The "struct kvm *kvm" parameter of kvm_tdp_mmu_get_root() is not used, so remove it. No functional change intended.
