[Qemu-devel] [PATCH 11/11] ahci: spawn controller on demand

[Alexander Graf <agraf@suse.de>]

When we add a device using -drive to the guest, we also need to create a
new SATA bus to handle the device. This patch adds a function call that
every machine that likes to have IF_SATA support can call to get full
device creation by keeping the actual qdev code clean.
