[PATCH 31/36] vhost-vdpa: vhost_vdpa_alloc_domain() should be using a const struct bus_type *

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

The function, vhost_vdpa_alloc_domain(), has a pointer to a struct
bus_type, but it should be constant as the function it passes it to
expects it to be const, and the vhost code does not modify it in any
way.

Note, this is a patch that is a prepatory cleanup as part of a larger
series of patches that is working on resolving some old driver core
design mistakes.  It will build and apply cleanly on top of 6.3-rc2 on
its own, but I'd prefer if I could take it through my driver-core tree
so that the driver core changes can be taken through there for 6.4-rc1.
