Subject: [PATCH 4.19 51/72] drm/msm: fix shutdown hook in case GPU components failed to bind
Date: Mon, 29 Mar 2021 09:58:27 +0200 [thread overview]
Message-ID: <20210329075611.960226403@linuxfoundation.org> (raw)
In-Reply-To: <20210329075610.300795746@linuxfoundation.org>
From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
[ Upstream commit 623f279c77811475ac8fd5635cc4e4451aa71291 ]
If GPU components have failed to bind, shutdown callback would fail with
the following backtrace. Add safeguard check to stop that oops from
happening and allow the board to reboot.
