Subject: [ 08/61] drm sis: initialize object_idr

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Márton Németh <nm127@...email.hu>

commit 648ccc7d35e3416fdc739d2e520e85de3125361b upstream.

The filed object_idr of struct drm_sis_private was introduced with
commit http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=6de8a748881f1cd9d795454da2b6db616d5ca3d7 .

The idr_init(&dev->object_name_idr) is called instead of
idr_init(&dev_priv->object_idr) by mistake, leaving object_idr
uninitialized. Correct this.

This patch was not tested because of lack of hardware.
