Everyone is entitled to his own opinion. While skimming the patches
terms like horrid, abomination, brain damaged does not really get me
motivated in reviewing it let alone accepting it. Especially when I just
start my vacation, but you could not have known ;-)

It is maybe 1:1 but it assures that whatever is in the priv structures
in only accessible in chip.c. Why would that not offer any real separation.

Ok. This needs to be looked at, but as I recall sbwad is only changing
when needed. All IO occurs under claimed host lock so I don't expect
there is a bug here, but will look at it more closely.

Now this is where a commit message would really help to explain your
train of thought. What is obvious to you, may not be to others. For
instance changing the order of parameters in a function is simply absurd
although that is my opinion.

I have a decent amount of SDIO chipsets so count on it that I will run
this patch series when I return from my vacation.
I just noticed some earlier reactions and it seems your are easily
offended starting to use *star* quotes. No need to start shouting. There
is stuff in there that I am happy to acknowledge, but some I think is a
matter of taste. Although mostly there are no arguments given to get the
discussion going. I am sure you have them in mind so don't qualm and
just spew them.
