[Qemu-devel] [PATCH v4 25/32] blockdev: Separate raw probe from its driver

[Colin Lord]

Completes the separation of the raw probe from the raw driver. The
raw probe now returns the format in addition to the score, allowing
correlation of the score and driver without the probe function being
part of the driver itself.
