Subject: hw/vfio/ccw: Remove pointless S390CCWDevice variable
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4b447883ede2d75960f2c02856e68710d6155268;p=qemu.git

hw/vfio/ccw: Remove pointless S390CCWDevice variable

QOM parenthood relationship is:

  VFIOCCWDevice -> S390CCWDevice -> CcwDevice -> DeviceState

No need to double-cast, call CCW_DEVICE() on VFIOCCWDevice.
