From 0fbddcecf23dcc311b42d9faf87dc2656dadd62a Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Wed, 22 Apr 2020 15:07:10 +0200 Subject: [PATCH] arm/virt: Fix virt_machine_device_plug_cb() error API violation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. virt_machine_device_plug_cb() passes @errp to cryptodev_builtin_sym_close_session() in a loop. Harmless, because cryptodev_builtin_sym_close_session() can't actually fail. Fix by dropping its Error ** parameter.
