Hi Laurent,
This commit uses a mailing list email, probably due to DKIM/SPF issues:
Author: Philippe Mathieu-Daudé via <qemu-devel@nongnu.org>

I think the policy is to reject such pull requests and fix the
authorship. Could you update your pull request and resend?

Thanks!

Stefan

Thank you Stefan.

Normally I have a pre-publish-send-email to check that, but it didn't fail in the expected way...

I re-send the PR.

[PULL 1/8] hw/virtio/vhost-shadow-virtqueue: Silence GCC error "maybe-uninitialized"

[Laurent Vivier]

From: Bernhard Beschow <shentey@gmail.com>

GCC issues a false positive warning, resulting in build failure with -Werror:

  In file included from /usr/include/glib-2.0/glib.h:114,
                   from src/include/glib-compat.h:32,

  cc1: all warnings being treated as errors

There is actually no problem since "elem" is initialized in both branches.
Silence the warning by initializig it with "NULL".

$ gcc --version
gcc (GCC) 12.2.0
