Subject: [ 22/49] drm/ast: fix the ast open key function

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dave Airlie <airlied@...hat.com>

commit 2e8378136f28bea960cec643d3fa5d843c9049ec upstream.

When porting from UMS I mistyped this from the wrong place, AST noticed
and pointed it out, so we should fix it to be like the X.org driver.
