File libparted-dont-warn-if-no-HDIO_GET_IDENTITY.patch of Package parted.3441

Subject: libparted: Don't warn if no HDIO_GET_IDENTITY ioctl
References: bsc#964012, bsc#1001967
Patch-mainline: Submitted, 2016-10-04 11:37 UTC+2 to parted-devel

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.
