[Qemu-devel] [PATCH for-2.3 2/3] sdhci: Make device "sdhci-pci" unavailable with -device

[Markus Armbruster <armbru@redhat.com>]

Due to misuse of drive_get_next(), -device sdhci can connect to a
-drive if=sd,...  If you can't see what's wrong here, check out the
FIXME in sdhci_initfn() and the commit that added it.

We can't fix this in time for the release, but since the device is new
in 2.3, we can disable it before this mistake becomes ABI: set
cannot_instantiate_with_device_add_yet.
