From df8658de43db242ea82183d75cc957c2b0fa013a Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Fri, 14 Jul 2017 09:50:40 +0200 Subject: [PATCH] spapr: fix memory leak in spapr_core_pre_plug() In case of error, we must ensure the dynamically allocated base_core_type is freed, like it is done everywhere else in this function. This is a regression introduced in QEMU 2.9 by commit 8149e2992f78.
