[PATCH 04/15] drm/i915: dev_priv cleanup in i915_gem_gtt.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>

Started with removing INTEL_INFO(dev) and cascaded into a quite
big trickle of function prototype changes. Still, I think it is
for the better.
