What one?  Your thises and thats are confusing.

If you think that "firmware/memmap: Move kobject initialisation before
kobject_add()" should still be applied then I'd disagree.  Adding a
GFP_KERNEL allocation into kobject_init() was a fairly significant
backward step.  It's _good_ that kobject_init() can be called this
early.  Let us strive to retain that robustness.
