[parted-devel] [PATCH 4/8] libparted: check return value from ped_geometry_init

[Petr Uzel]

If ped_geometry_init() failed in ped_disk_set_partition_geom(),
then new_geom remains uninitialized, but still later used, which
leads to unexpected results.

* libparted/disk.c (ped_disk_set_partition_geom): Check return
value from ped_geometry_init().
