From c61d1d9e4976d127a73bec14376d8e828491f62c Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Wed, 22 Apr 2020 15:07:14 +0200 Subject: [PATCH] xen/pt: Fix flawed conversion to realize() The conversion of xen_pt_initfn() to xen_pt_realize() blindly replaced XEN_PT_ERR() by error_setg(). Several error conditions that did not fail xen_pt_initfn() now fail xen_pt_realize(). Unsurprisingly, the cleanup on these errors looks highly suspicious. Revert the inappropriate replacements.
