From 5f508c43a7648baa892528922402f1e13f258bd4 Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Fri, 8 May 2015 17:38:52 +0200 Subject: [PATCH] MIPS: KVM: Fix unused variable build warning As kvm_mips_complete_mmio_load() did not yet modify PC at this point as James Hogans explained the curr_pc variable and the comments along with it can be dropped.
