pr_* macros replaced with dev_* as they are more preffered over pr_*.

In this patch, it's not trivial conversion, so it's not bad to spend
more words to explain how you did it. Nevertheless...

yes , it looks bad. we can have a pointer to the card in the struct of the managers.

Better to rather fix the type of hw.base_mem field.

Last but not least, try to align the subject line with other commits
to this driver. See git log and compare with yours.

thanks,

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

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

Do you see what was missing?
