Subject: [PATCH 57/75] libparted: Don't warn if no HDIO_GET_IDENTITY ioctl
Fully virtualized Xen VMs (HVM) use Linux IDE devices which don't
support the HDIO_GET_IDENTITY ioctl. EINVAL is returned, a warning
is printed and the device model is set to "Generic IDE" in that
case. The problem is seeing the warning all the time. So drop it
for this case.
