From a343c9b7673e2228bc8a9ac65aae42140f6f9977 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 16 Jul 2013 13:03:29 +0200 Subject: [PATCH] KVM: introduce __kvm_io_bus_sort_cmp kvm_io_bus_sort_cmp is used also directly, not just as a callback for sort and bsearch. In these cases, it is handy to have a type-safe variant. This patch introduces such a variant, __kvm_io_bus_sort_cmp, and uses it throughout kvm_main.c.
