Delay matches of platform devices until late_initcall, when we are sure that all built-in drivers have been registered already. This is needed to prevent deferred probes because of some dependencies' drivers not having registered yet.
I have to say I'm still not 100% clear that special casing platform devices makes sense here - I can see that platform devices are usually the first devices to instantiate but there are other kinds of devices and it's not obvious what the benefit of specifically picking out platform devices as opposed to just deferring all devices is.
Some existing devices cannot be deferred without redesigning things quite a bit.
What I was talking about, though, was to use an opt-in mechanism for that which could be set for all platform devices, for example, by default, but it might be set for other bus types too if that's useful.
Thanks, Rafael
