[Intel-gfx] [PATCH 01/10] drm/i915/lvds: Rename intel_lvds to intel_lvds_encoder
Jani Nikula
jani.nikula at intel.com
Fri Oct 19 13:51:43 CEST 2012
In preparation for introducing intel_lvds_connector to move some of the
LVDS specific storage away from drm_i915_private, first rename the encoder
to avoid potential confusion.
Based on earlier work by Chris Wilson <chris at chris-wilson.co.uk>
