Indeed he is not. And while his minor nitpicks can sometimes be worth
the effort, it's less useful for him to start making value judgements
about removing drivers which have _theoretically_ been replaced by new
code, but which are actually still being used in some cases.

I know what needs doing to clean the tree up -- and removing the older
chip drivers is very far from the top of my todo list. If you really
want to accelerate their demise, add a #warning and a printk saying "You
should no longer be using this driver -- try using jedec_probe or
cfi_probe instead and contact the linux-mtd list if that fails".

That would be much appreciated -- and _useful_. We need to add sysfs
support to MTD devices, we need to revamp the way that the chip probe
code hands off to the back-end chip drivers, and in doing so get rid of
the use of inter_module_crap(), and we need to audit the module
refcounting while we're at it.

I'm hoping I'll get a week or two some time soon to sit down and
actually concentrate on that, because it's not something I can really
pick at piecemeal and it wants proper testing. But if Adrian wants to
have a go, that would be wonderful.

But picking away at what looks like low-hanging fruit without a real
understanding of what's going on doesn't really help much.
