Change kzalloc + kcalloc to just kzalloc with a flexible array member.

Add __counted_by for extra runtime analysis when requested.

Shuffle some code in probe to provide a clearer picture.

That's a lot of different things all at once, please do not do that.
Remember, kernel changes need to be "one patch per logical thing".

Maybe I overstated it. It's not a huge change. By shuffle I mean move
assignments up, which is partially a requirement of __counted_by

Can you just convert one driver at a time please?  This should be a
patch series.
