the card in other functions

You need to explain why this change is needed.  The above text shows
what it'd do, but it doesn't give any explanation to convince why this
patch must be merged in.  In this case, it's a preliminary patch for
the changes to convert to dev_*() later.  It's the most important bit,
so don't forget it.


thanks,

Takashi

then do i mention in the commit that it is the preliminary patch for the later changes to dev_* ?
i was thinking that we can get a reference of the card from other functions which are using struct hw
is a reason by itself.

If the purpose of this patch is so, just write what it'll be used
for.

If the purpose of this patch is rather broader, just write what it'll
be used for.

Do you see what was missing?
