From 84ebd3e8c7d4fe955b359b9aac84395907b0412e Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 16 Aug 2017 16:08:48 +0200 Subject: watchdog/wdt_diag288: Mark diag288 watchdog as non-hotpluggable QEMU currently aborts when the user tries to hot-unplug a diag288 device: $ qemu-system-s390x -nographic -nodefaults -S -monitor stdio QEMU 2.9.92 monitor - type 'help' for more information (qemu) device_add diag288,id=x (qemu) device_del x ** ERROR:qemu/qdev-monitor.c:872:qdev_unplug: assertion failed: (hotplug_ctrl) Aborted (core dumped) The device is not designed as hot-pluggable (it should only be used via the "-watchdog" parameter), so let's simply remove the possibility to hotplug it to prevent that users can run into this ugly situation.
