From 058276303dbc4ed089c1f7dad0871810b1f5ddf1 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 17 May 2010 16:30:42 -0700 Subject: DMAENGINE: extend the control command to include an arg This adds an argument to the DMAengine control function, so that we can later provide control commands that need some external data passed in through an argument akin to the ioctl() operation prototype.
