Thanks for the patch. I applied it to for-next[1], since the following
commits at v6.4 kernel have already allowed to keep it as constant (your
absolute work!).

* commit ad8685d0f61a ("driver core: bus: constify bus_unregister()")
* commit 00c4a3c47da7 ("driver core: bus: constantify bus_register()")
* commit d492cc2573a0 ("driver core: device.h: make struct bus_type a const *")
