And even then, don't do it and try to do something else. Platform devices are really abused, don't perpetuate it " In addition, rather than a plain-vanilla init/exit, this patch provides 3 steps in the initialization (ACPI scan, probe, startup) which makes it easier to verify hardware support for SoundWire, allocate required resources as early as possible, and conversely help make the startup() callback lighter-weight with only hardware register setup.
