[Qemu-devel] [PATCH] spapr: return from post_load method when RTC import fails

["Cédric Le Goater" <clg@kaod.org>]

The error value can be squashed by the section handling radix migration.
Simply bail out if an error occurs when the RTC offset is imported.

Fixes: d39c90f5f3ae ("spapr: Fix migration of Radix guests")
