Among the different device id structures <linux/virtio_pci_legacy.h>
only uses struct virtio_device_id. Include <linux/device-id/virtio.h>
instead of <linux/mod_devicetable.h> to provide that which is more
lightweight and doesn't introduce that many dependencies.

The users of <linux/virtio_pci_legacy.h> also don't rely on this header
to provide the full plethora of definitions. (There are only
drivers/vdpa/alibaba/eni_vdpa.c and drivers/virtio/virtio_pci_common.c
using pci_device_id and these include <linux/pci.h> which is enough to
get it.)

Hello,

note that <linux/device-id/virtio.h> only exists since v7.2-rc2, so make
sure your base is new enough when applying this patch.

Best regards
Uwe

In case you postponed applying this patch because of that, I think it's
safe to assume that <linux/device-id/virtio.h> now exists in the
relevant tree.

The patch still applies fine to next-20261110, can you please apply it?

Best regards
Uwe
