Once code is in mainline, it's in mainline. It doesn't mean things will work, lol. It means things will rather regularly break, because many people modify shared code you depend on without ability to test on your particular HW. Not saying pushing mainline is bad. But assumption there's any kind of "support" is wrong. Code is there. That's all. You have to support it if you want it to work. (This is very particular to HW/drivers support, Linux core is supported well, I guess.)
