sd/pxa2xx_mmci: Fix to realize "pxa2xx-mmci" device
pxa2xx_mmci_init() creates a "pxa2xx-mmci" device, but neglects to realize it. Affects machines akita, borzoi, connex, mainstone, spitz, terrier, tosa, verdex, and z2. In theory, a device becomes real only on realize. In practice, the transition from unreal to real is a fuzzy one. The work to make a device real can be spread between realize methods (fine), instance_init methods (wrong), and board code wiring up the device (fine as long as it effectively happens on realize). Depending on what exactly is done where, a device can work even when we neglect to realize it. This one appears to work. Nevertheless, it's a clear misuse of the interface. Even when it works today (more or less by chance), it can break tomorrow. Fix by realizing it right away. Visible in "info qom-tree"; here's the change for akita: /machine (akita-machine) [...] /unattached (container) [...] + /device[5] (pxa2xx-mmci) + /pxa2xx-mmci[0] (qemu:memory-region) + /sd-bus (pxa2xx-mmci-bus) [rest of device[*] renumbered...] Fixes: 7a9468c Cc: Andrzej Zaborowski <balrogg@gmail.com> Cc: Peter Maydell <peter.maydell@linaro.org> Cc: qemu-arm@nongnu.org Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20200609122339.937862-4-armbru@redhat.com>
