From 8f8419d3255365121e3596307b98ab3d6dcbdf1a Mon Sep 17 00:00:00 2001 From: Samuel Tardieu Date: Tue, 19 Dec 2023 19:22:12 +0100 Subject: tcg: Make the cleanup-on-error path unique By calling `error_setg_errno()` before jumping to the cleanup-on-error path at the `fail` label, the cleanup path is clearer.
