From c4ace5daf4ff726402b13f1ababf2ad0e0ceec65 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Thu, 28 May 2015 09:28:22 +0100 Subject: [PATCH] hvc_xen: avoid uninitialized variable warning Older compilers don't recognize that "v" can't be used uninitialized; other code using hvm_get_parameter() zeros the value too, so follow suit here.
