Besides, isn't this the intended use case for "select"? A config symbol

VIRTIO_F_VERSION_1 is a bit number. Use BIT_ULL() with mask
conditionals.
Also, in mlx5_vdpa_is_little_endian() use BIT_ULL for consistency with
the rest of the code.

new XillyUSB device files xillyusb_* instead of
xillybus_* may appear awkward. But I'm quite sure that no single user
will ever thank me or anyone else for merging them. Maybe the formality
is still important enough to do this anyhow...?

don't expect that to reduce the total amount of code lines, nor make it
friendlier to read. But this will reuse the existing device class name
instead of creating a new one. Does this sound like a good idea?

Hello Randy,
The new driver doesn't depend on XILLYBUS, so the patch puts it
correctly outside the "if XILLYBUS" clause. It indeed looks like a
mistake, but it isn't. :)
Thanks for paying attention to this.
