From bcfc906be47a88803307cd6b665dc4c26fdd6dd2 Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Tue, 19 Oct 2021 09:15:32 +0200 Subject: [PATCH] qdev/qbus: remove failover specific code Commit f3a850565693 ("qdev/qbus: add hidden device support") has introduced a generic way to hide a device but it has modified qdev_device_add() to check a specific option of the failover device, "failover_pair_id", before calling the generic mechanism. It's not needed (and not generic) to do that in qdev_device_add() because this is also checked by the failover_hide_primary_device() function that uses the generic mechanism to hide the device.
