[PATCH] scc_pata: add ->{in,out}put_data methods (take 2)

From: Bartlomiej Zolnierkiewicz
Date: Wed Apr 16 2008 - 18:28:54 EST



v2:

* Update ->{in,out}_data methods to take 'struct request *rq' argument
(thanks to Stephen Rothwell for catching it).

There should be no functional changes caused by this patch.
