From 6353218b8c54dc6be6abb01c07a087add07ee5ce Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Wed, 17 Oct 2018 10:26:42 +0200 Subject: vl: Clean up error reporting in parse_add_fd() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Calling error_report() in a function that takes an Error ** argument is suspicious. parse_add_fd() does that, and then fails without setting an error. Its caller main(), via qemu_opts_foreach(), is fine with it, but clean it up anyway. Also change call of cleanup_add_fd(), which can't fail, for symmetry.
