From bd93a50e4dbae108a55a228bba1a69a2314096fb Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Wed, 30 Sep 2015 23:00:43 +0300 Subject: [PATCH] drm/i915: rename INSTDONE to GEN2_INSTDONE We have a bunch of INSTDONE registers for different platforms and purposes and it's not immediately clear which instance they are just by looking at the register name. This one was added on GEN2, where it was the only INSTDONE register, so mark it as such.
