Greg Kroah-Hartman 86438841e4 dma-debug: make dma_debug_add_bus take a const pointer

The driver core now can handle a const struct bus_type pointer, and the
dma_debug_add_bus() call just passes on the pointer give to it to the
driver core, so make this pointer const as well to allow everyone to use
read-only struct bus_type pointers going forward.
