Subject: [PATCH 04/28] drm/i915/selftests: Replace mock_file hackery with drm's true fake
Date: Thu,  7 Nov 2019 08:12:28 +0000	[thread overview]
Message-ID: <20191107081252.10542-4-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20191107081252.10542-1-chris@chris-wilson.co.uk>

As drm now exports a method to create an anonymous struct file around a
drm_device for internal use, make use of it to avoid our horrible hacks.
