[Qemu-devel] [PATCH 2/2] vfio/ccw: fix initialization of the Object DeviceState pointer in the common base-device
Posted by Dong Jia Shi 8 years, 6 months ago 
Commit 7da624e2 ("vfio: Test realized when using VFIOGroup.device_list
iterator") introduced a pointer to the Object DeviceState in the VFIO
common base-device and skiped non-realized devices as we iterate
VFIOGroup.device_list. While it missed to initialize the pointer for
the vfio-ccw case. Let's fix it.

Fixes: 7da624e2 ("vfio: Test realized when using VFIOGroup.device_list
                  iterator")

s/skiped/skipped/

I'll fix this while applying.
