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.

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

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.

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

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

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