[PULL 06/11] vfio/ccw: Fix the missed unrealize() call in error path

Posted by Thomas Huth 5 months ago

From: Zhenzhong Duan <zhenzhong.duan@intel.com>

When get name failed, we should call unrealize() so that
vfio_ccw_realize() is self contained.

Fixes: 909a6254eda ("vfio/ccw: Make vfio cdev pre-openable by passing a file handle")
