From 41c14057a8aa4918a5b5b1f5954544c9c9ac7c9d Mon Sep 17 00:00:00 2001
From: Gurchetan Singh <gurchetansingh@chromium.org>
Date: Tue, 1 Nov 2016 09:53:06 -0700
Subject: [PATCH 4/8] CHROMIUM: drm: Allow render node access to KMS getters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We need to query the KMS API to present an accurate view of overlay
formats in Android (see CL:405019). With the exception of
SET_CLIENT_CAP, these ioctls are getters.
SET_CLIENT_CAP is allowable with render nodes since it only presents
a different version of the drm core to userspace when modified.
BUG=chromium:795946
TEST=Get a little farther
Conflicts:
drivers/gpu/drm/drm_ioctl.c
...due to DRM_IOCTL_SET_CLIENT_CAP having DRM_UNLOCKED in 4.14.
