Subject: [PATCH AUTOSEL 4.9 235/251] media: exynos4-is: Fix recursive locking in isp_video_release()
Date: Thu, 16 Jan 2020 12:36:24 -0500
Message-ID: <20200116173641.22137-195-sashal@kernel.org> (raw)
In-Reply-To: <20200116173641.22137-1-sashal@kernel.org>
From: Seung-Woo Kim <sw0312.kim@samsung.com>
[ Upstream commit 704c6c80fb471d1bb0ef0d61a94617d1d55743cd ]
>From isp_video_release(), &isp->video_lock is held and subsequent
vb2_fop_release() tries to lock vdev->lock which is same with the
previous one. Replace vb2_fop_release() with _vb2_fop_release() to
fix the recursive locking.
Fixes: 1380f5754cb0 ("[media] videobuf2: Add missing lock held on vb2_fop_release")
