Heads up: checking in change to ata-card.c

[M. Warner Losh]

Here's a better patch, basesd on wpaul's input.  Bill, can you try it
an see if it works for you?  If so, i would be better to commit this
one.  If not, I'll work with you to fix it. 

If you are uninterested in working with us to get things in, then your
patch will not lasts the evening as such an approach is unacceptibe.
