Subject: [PATCH 5/5] v4l: Remove struct v4l2_file_operations::ioctl
Date: Thu, 29 Apr 2010 05:42:44 +0200	[thread overview]
Message-ID: <1272512564-14683-6-git-send-regression-fweisbec@gmail.com> (raw)
In-Reply-To: <alpine.LFD.2.00.1004280750330.3739@i5.linux-foundation.org>

No more drivers use the bkl'ed callback, now drop it for good.
