[ 35/78] drm/i915: treat src w & h as fixed point in sprite handling code

From: Greg KH
Date: Wed Apr 11 2012 - 20:00:44 EST


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

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

From: Jesse Barnes <jbarnes@xxxxxxxxxxxxxxxx>

commit b4db1e35ac59c144965f517bc575a0d75b60b03f upstream.

This was missed when we converted the source values to 16.16 fixed point.
