i have a doubt regarding this :- 
in the snd_card_new()  card->dev is being assigned with &pci->dev , 
then are not they the same ?

i was trying to get some way of finding out the reference of card->dev from the resource manager ,
but ...  :( 
i will try again and if i cant find any way i will ask for some hint from you.

i am still a newbie , and started this  pr_* to dev_* on your inspiration , and i hope
you will not be irritated by my patches . :)

thanks
sudip
