[PATCH 2/2] qdev/qbus: remove failover specific code |
Date: |
Tue, 19 Oct 2021 09:15:32 +0200 |
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.
