Subject: [PATCH AUTOSEL 4.9 20/25] drm/sun4i: Set device driver data at bind time for use in unbind
Date: Tue, 7 May 2019 01:41:17 -0400 [thread overview]
Message-ID: <20190507054123.32514-20-sashal@kernel.org> (raw)
In-Reply-To: <20190507054123.32514-1-sashal@kernel.org>
From: Paul Kocialkowski <paul.kocialkowski@bootlin.com>
[ Upstream commit 02b92adbe33e6dbd15dc6e32540b22f47c4ff0a2 ]
Our sun4i_drv_unbind gets the drm device using dev_get_drvdata.
However, that driver data is never set in sun4i_drv_bind.
Set it there to avoid getting a NULL pointer at unbind time.
Fixes: 9026e0d122ac ("drm: Add Allwinner A10 Display Engine support")
