Subject: [PATCH 4.9 15/61] Revert "drm/rockchip: Allow driver to be shutdown on reboot/kexec"
Date: Thu, 20 Dec 2018 10:18:15 +0100	[thread overview]
Message-ID: <20181220085844.341672426@linuxfoundation.org> (raw)
In-Reply-To: <20181220085843.743900603@linuxfoundation.org>

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

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

From: Brian Norris <briannorris@chromium.org>

commit 63238173b2faf3d6b85a416f1c69af6c7be2413f upstream.

This reverts commit 7f3ef5dedb146e3d5063b6845781ad1bb59b92b5.

It causes new warnings [1] on shutdown when running the Google Kevin or
Scarlet (RK3399) boards under Chrome OS. Presumably our usage of DRM is
different than what Marc and Heiko test.

We're looking at a different approach (e.g., [2]) to replace this, but
IMO the revert should be taken first, as it already propagated to
-stable.
