Subject: [PATCH 1/9] drm/dp: Use non-cyclic idr
Date: Tue, 23 Jul 2019 19:28:00 -0400 [thread overview]
Message-ID: <20190723232808.28128-2-sunpeng.li@amd.com> (raw)
In-Reply-To: <20190723232808.28128-1-sunpeng.li-5C7GfCeVMHo@public.gmane.org>
From: Leo Li <sunpeng.li@amd.com>
In preparation for adding aux devices for DP MST, make the IDR
non-cyclic. That way, hotplug cycling MST devices won't needlessly
increment the minor version index.
