Andrew already asked you to provide more background on what you need
this part for. Do you have a specific driver you need to disable?
Can't you do the same thing using initcall_blacklist?

It looks like the denylist is only introduced in the same patch?
That sounds more useful, but would better be done in a separate
change, and also needs a proper changelog text.

I can reproduce it independently of this patch.
It looks like `panic_null_reference_constructed`, added the other day
-- I will send the patch.
