Sorta. I want to be paranoid when loading the microcode image file and
in patch 3/7 ( I
propagate the error in case loading the microcode fails. If we don't
cleanup here, the driver remains loaded and takes up resources. And if
you load it again, you get a sysfs warning about duplicated entries.

Sorry about that, I did not mean to bypass/offend you in any way.

Do you need the patches rediffed against a some tree of yours?

@Ingo: please disregard my pull request from today:

Guys, sorry again if I've caused any trouble.
