It's no longer possible to load i915, as the GPU can be driven by the xe driver instead. The new behavior will return -EPROBE_DEFER, and wait for a compatible driver to be loaded instead of modprobing i915. Converting all drivers at the same time is a lot of work, instead we will convert each user one by one.
