commit 5efb3e2838536832c9b6872512e6b6daf592cee9
Author: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Date: Wed Apr 9 13:28:53 2014 +0300
drm/i915/chv: Add cursor pipe offsets
the only difference between i9xx_update_cursor() and ivb_update_cursor()
was the hsw+ pipe csc handling. Let's unify them and we can rid
outselves of some duplicated code.
