Subject: [PATCH for v4.9 02/13] media: v4l2-compat-ioctl32.c: add missing VIDIOC_PREPARE_BUF
Date: Wed, 14 Feb 2018 12:48:19 +0100 [thread overview]
Message-ID: <20180214114830.27171-3-hverkuil@xs4all.nl> (raw)
In-Reply-To: <20180214114830.27171-1-hverkuil@xs4all.nl>
From: Hans Verkuil <hans.verkuil@cisco.com>
commit 3ee6d040719ae09110e5cdf24d5386abe5d1b776 upstream.
The result of the VIDIOC_PREPARE_BUF ioctl was never copied back
to userspace since it was missing in the switch.
