[Qemu-devel] [PATCH v6 1/8] virtio-blk: don't use pointer for configuration.

[fred.konrad@greensocs.com]

From: KONRAD Frederic <fred.konrad@greensocs.com>

The configuration field must not be a pointer as it will be used for virtio-blk
properties. So *blk is replaced by blk in VirtIOBlock structure.
