[Qemu-devel] [PULL 8/9] qdev: ignore GlobalProperty.errp for hotplugged devices

[Eduardo Habkost]

From: Greg Kurz <address@hidden>

This patch ensures QEMU won't terminate while hotplugging a device if the
global property cannot be set and errp points to error_fatal or error_abort.

While here, it also fixes indentation of the typename argument.
