[Intel-gfx] [PATCH 18/22] drm/i915: Use dev_priv consistently through the intel_frontbuffer interface

Chris Wilson chris at chris-wilson.co.uk
Wed Jul 27 11:14:56 UTC 2016


Rather than a mismash of struct drm_device *dev and struct
drm_i915_private *dev_priv being used freely within a function, be
consistent and only pass along dev_priv.
