From 4e48e7f1f18a7c6fcacc823214effde1cf7cd7bc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Radim=20Kr=C4=8Dm=C3=A1=C5=99?= Date: Thu, 18 May 2017 19:37:32 +0200 Subject: [PATCH] KVM: x86: prevent uninitialized variable warning in check_svme() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit get_msr() of MSR_EFER is currently always going to succeed, but static checker doesn't see that far. Don't complicate stuff and just use 0 for the fallback -- it means that the feature is not present.
