From c3e35409b54e8833ab936e667e3e7fcb8bdace00 Mon Sep 17 00:00:00 2001 From: Shannon Zhao Date: Mon, 2 Dec 2019 15:42:11 +0800 Subject: [PATCH] KVM: ARM: Call hyp_cpu_pm_exit at the right place It doesn't needs to call hyp_cpu_pm_exit() in init_hyp_mode() when some error occurs. hyp_cpu_pm_exit() only needs to be called in kvm_arch_init() if init_subsystems() fails. So move hyp_cpu_pm_exit() out from teardown_hyp_mode() and call it directly in kvm_arch_init().
