Subject: [PATCH 02/19] drm: track planes in drm_mode_group structure
Date: Thu, 12 Apr 2012 14:19:27 -0400	[thread overview]
Message-ID: <1334254784-3200-3-git-send-email-ihadzic@research.bell-labs.com> (raw)
In-Reply-To: <1334254784-3200-1-git-send-email-ihadzic@research.bell-labs.com>

drm_mode_group structure (meant for subgrouping) of display
resources didn't include planes, which made it impossible to
do any subgrouping of planes. This patch rectifies the problem.
