Subject: drm/i915: create dev_priv->dri1 dragon dungeon^W^W sub-struct
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8781342df72fcc37f2aebd43d3a293b0a343806d;p=linux-beck.git

drm/i915: create dev_priv->dri1 dragon dungeon^W^W sub-struct

... and shove allow_batchbuffer in there. More dragons will
follow suit.

There's the curious case that we allow this for KMS ...
