[Qemu-devel] [PATCH 16/31] xen: Clean up pci_piix3_xen_ide_unplug()'s test for "not a CD"

[Kevin Wolf <kwolf@redhat.com>]

From: Markus Armbruster <armbru@redhat.com>

pci_piix3_xen_ide_unplug() unplugs only disks, not CD-ROMs.  It peeks
into the DriveInfo's BlockDriverState to distinguish between the two.
Unclean; use DriveInfo member media_cd, like xen_config_dev_blk().
