From 1dfd9754cd55e424f247d9a2e855ad384e3e90ef Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 6 Sep 2010 14:44:14 +0100 Subject: Revert "drm/i915: Unreference object not handle on creation" This reverts commit 86f100b136626e91f4f66f3776303475e2e58998. The kref API requires the handlecount to be initialised to one on object creation (so that kref_get() doesn't complain upon first use) so the dalliance in the drivers is required in order to sink the initial floating reference.
