    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.

    Yes, will do.

    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.
