From 25f2895e0e437a3548f9794846001fb5d5ab853d Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Thu, 11 Dec 2014 12:07:53 +0000 Subject: target-arm: Check error conditions on kvm_arm_reset_vcpu When resetting a VCPU we currently call both kvm_arm_vcpu_init() and write_kvmstate_to_list(), both of which can fail, but we never check the return value. The only choice here is to print an error an exit if the calls fail.
