Message-Id: <20170429060702.6656-2-keithp@keithp.com>
Date:   Fri, 28 Apr 2017 23:06:58 -0700
From:   Keith Packard <keithp@...thp.com>
To:     linux-kernel@...r.kernel.org, Dave Airlie <airlied@...hat.com>,
        Daniel Vetter <daniel@...ll.ch>
Cc:     Keith Packard <keithp@...thp.com>, dri-devel@...ts.freedesktop.org
Subject: [PATCH 1/5] drm: Pass struct drm_file * to  __drm_mode_object_find

This will allow __drm_mode_object_file to be extended to perform
access control checks based on the file in use.

Suggested-by: Daniel Vetter <daniel.vetter@...ll.ch>
Signed-off-by: Keith Packard <keithp@...thp.com>
